Failed to logon?

[Ramses II CP]

I alternately get a 'failed to logon' error that returns more or less immediately, or a 'connection lost' error that takes about 30 seconds to come back. The first time I tried to login, it went fine, although the second time it threw the invalid CD key bit, but that is corrected.

Any hints? I'm searching the forum now, but I thought someone might know offhand.

edit: Sorted it out, thanks.
