Actaully, some people had this problem in the beta version; it was posted on their beta forums.
Since a clean uninstall + reinstall didn't fix the issue, I'll do a reg search/clean and remove all trillian instances, and then reinstall.
If it works, then it was a registry issue, as you suggested.
but if it doesn't, then something is wrong.
I've never had a problem like this before.
But something was changed from the 2.0 beta, to RC2 / final, to make this happen.
*edit* I just checked the official forums.
Other people are having this exact same problem, so it *IS* a bug of some sort.

still trying the clean install.
*edit again*
Clean install, clean registry wipe.
Problem still exists.
My friend sent me a 19 byte text file.
On his computer, it says I never received anything.
On mine it says "file : 19 bytes, received 19 bytes, progress: 100%, "file transfer active". But the file doesn't exist (well the file name does but it's 0 bytes), and trillian's CPU usage jumped up to 100% (usually it's around 5% or so). Eventualy, my friend's MSN reported "transfer failed", mine is still stuck at 100%.
If I try to close trillian with the transfer window still active, I get an invalid page fault in msn.dll
So this is definitely a bug in the program.
