I never played MP with this computer, so I tried to join a new server.
OK.
Then, I will assume that if your installation was from GoG, you applied for their unique on-line CD keys. Then there should be no problem like what you are having.
I'll further assume that you tried to join a few other servers with the same result? If so, I am stumped. Some servers have integrated special security measures (with the GameSpy authentication going down) that could be causing a problem for you and in those cases, you should contact the server admin for suggestions. (Most servers have forums for questions.)
