Cannot Run Downloads! - Please Help

I don't know if this is in the right place, but I'll post it anyway.

I've just downloaded the 1.5 patch for BF2, So it finished downloading so I clicked on it, clicked run where it says run or dont run, and then nothing happens. This is the first time its happened, so please help.

Check your antivirus/firewall isn't blocking it.

try saving it then running it.

If I'm not mistaken that patch is over 2GB. It will take a while for it to come up.

Nah it's 1.9GB but I ran it and then waited for a while and nothing happened.
