I fixed my AIM by blanking out the encryption (remove the opportunistic_encryption entirely) and manually entering port 5190.

I also manually entered the port info for Yahoo and instead of giving me a network error, it's been trying to login for almost 15 minutes now. Wonder how long I should give it?

EDIT: Yahoo died with a network error. Bah.

ANOTHER EDIT: I got Yahoo to work using port 80 instead of 5050.

I'm still working on MSN...
