If you are using Internet Explorer then you are highly likely to be logged out often. The site has be designed exclusively for FireFox [which I highly recommend as an alternative to Internet Explorer] with some support for IE. You should try clearing out your cookies before you log in to see if your browser isn't bloated with junk.

i'm using firefox,
I change some registry before to kill some programs that i cracked and somehow there's a registry that i wrongly deleted
looks like i need to reinstall firefox... :cry:
