Actually, I reinstalled the Mandrake Cooker, and it is working fine now. I think it had something to do with some packages not installed correctly. It works perfectly fine now, and also, GAIM works fine, and that was what I was using while I tried to get Kopete to work.
I like the integration of Kopete with KDE, since it is, well, a KDE program. Since it is working, I'm going to be using it!
