I've had Kopete for the last few years, and never had any problems with it before. A few weeks ago, it stopped accepting my password, and I haven't been able to log in since. any idea what the problem could be, and if it can be fixed?

Maybe some config file got messed up. Could you try running it from a terminal and check the output?

You can also try as a different user...

You might be talking about ICQ. The login changed, as AOL sold ICQ again. Just replace the default login server to login.icq.com and it should work again.
