Need Help! +REP

I sent you what to do in a pm:)

there might be a newer version of java or flash that you havt got have a look and check :D hope it helped

I dont think i had that problem so i cant help.

try waiting a couple mins with the white screen and when you load up the page don't go on other windows wait until the thing is finished loading

also try different worlds from different locations (like instead of usa 1 use europe or w/e)

edit:
jay no offence but why are you posting then if you never had the problem and can't help?

Sorry i didnt post my problem sorted thanks to Arch :)
