Trillian Professional, Anyone Know Stuff About Trillian?

[-cf-]

Well the name says it all, I'm having problems with Trillian. Most people hate the program but I don't see why, I like it. Plus it's better than using four seperate chat clients. Anyways I've never had this problem before until about 5 days ago. I open it up, and than 5 seconds later I get some error saying "KERNEL.DLL has caused an error and will no close, try restarting your computer blah blah blah" And all I have to do is move the error box out of the way and everything still seems to work. Or click close and have Trillian close, lol. But still it's annoying, that and the awkward problem of me not being able to see people's messages on ICQ? Strange eh? I'm using Trillian Professional, not sure if it is the same as all the shareware ones. Would appreciate some help.
