I got this from one of the Habbo Player Support workers. Its for check-in troubles. Sadly it did not solve mine, but it may help you. Here it is.
Firstly, we suggest you delete your temporary Internet files. You can do this by following the instructions below:
Close all open browser windows (a browser is what you use to look at the Internet, eg Explorer), except for one.
Go to the Tools menu, and click Internet Options
Click 'Delete Files...', then tick 'delete all offline content', and press OK
Now try loading Habbo Hotel again.
OTHER COMMON REASONS FOR PROBLEMS
There are a number of reasons why Habbo Hotel may not work for you.
The hotel may also be full, in which case we advise you to wait a few minutes then try to enter again.
You might be banned. If you see a message popping up saying you have been denied access. In this case, wait two hours, then retry. If you still can't get in, email us using the Contact Us form (choose 'Why have I been banned?'):
http://www.habbohotel.co.uk/habbo/en/help/contact/
Your computer may be out of memory. Try restarting your computer. Also, make sure you don't have too many other browser windows/programs open when you try to use Habbo Hotel.
Also, if you think you may be behind a firewall, make sure you talk to your administrator about having specific ports opened on it, so that you may use Habbo Hotel.
Caching: your ISP may be keeping an old copy of our site on its servers, there isn't much we can do about this, but it will usually update in a few hours,
Disconnected: you keep getting the 'Disconnected! Please reload Habbo Hotel' pop up. If this happens it means the connection between your computer and Habbo Hotel has broken. Sometimes you will still be able to speak and move about, but some parts of the hotel - like your Navigator or Console - might not work. Try reloading the hotel (Ctrl-R or F5). Since this problem is caused by the connection from your ISP (who you connect to the Internet through, e.g. AOL, Freeserve etc) to the Internet breaking, it may due to high Internet traffic and so just trying later might help. If you use a very popular ISP that has lots of users and gets very busy, you may get disconnected more often. It may even be worth switching to a different ISP. Finally, if your Friends List is really, really long it might be a good idea to remove some of the people you don't talk to anymore.
Script errors: you get pop ups saying 'script error' or 'this file is not a director file' etc. This sometimes happens if we have added new things to the hotel, like new bits of furni in the Catalogue. This should solve the problem - close all Internet Explorer (IE) windows. Open a new IE window. Choose 'Internet Options' in the 'Tools' menu on the top menu bar. Choose 'Temporary Internet Files' in the window that opens. Click on the button labelled 'Delete Files...'. Click on 'OK' to empty the locally cached files. Close the IE window. When you go into the hotel next it will take a bit longer to load, but the script errors should not occur.
Black screen: you click on 'Check in' and all you get is a black screen. Most likely there is a problem with your Shockwave download. The best thing to do is go to the Habbo Hotel home page and download it again. Then install it.
Security risk pop up: a scary looking pop up appears warning of a security risk. This is a normal security pop up from Shockwave. To stop it appearing again, just tick the third box and 'OK'.
Never connect: you type in your Habbo name and password and it just keeps saying 'connecting', until you eventually get the 'disconnected' pop up. Most likely the hotel is full up, so wait a while and try again. The hotel gets busiest after school and at the weekends. However, if you got a pop up the last time you came to the hotel saying that you'd been refused permission, your Habbo is banned and that is why you can't get in. Or is someone else who uses the same computer has been banned permanently, they may have got the computer banned too. If you think this is the case, please ask everyone who uses the computer what their Habbo names are and email them to us so we can check.
Out of memory alert: when loading Habbo Hotel, or afterwards, you may get an alert saying 'Out of memory even after purging all cast members ..'. Habbo Hotel has loads of graphics that consume your computer memory (RAM) and the alert means that there is not enough free memory for Habbo to work. In many cases, the following tricks help:
Close your browser and other applications (such as word processor, spreadsheet, mp3-player). Now open your browser and try Habbo Hotel again.
Restart the computer. Often, when your computer has been in use for long periods, its memory gets full.
Invisible Habbos or the Catalogue isn't showing: this due to Shockwave files not downloading properly to your computer, to rectify this problem, do the following:
Close all open browser windows, except for one
Go to the Tools menu, and click internet options
Click "Delete Files...", then tick "delete all offline content, and press okay
Now try loading Habbo Hotel again.
PH boxes instead of furni: this is due to Shockwave files not downloading properly to your computer, to rectify this problem, do the following:
Close all open browser windows, except for one
Go to the Tools menu, and click internet options
Click "Delete Files...", then tick "delete all offline content, and press okay
Now try loading Habbo Hotel again.
Can't get into the rooms in the hotel: this is probably because the room you are trying to enter is full (even if it shows as not full, the Navigator takes a while to update). Try other, less busy rooms.
Thanks
