I have pretty much the same problem, exept it tells me "Unable to connect to server" every time I try to connect to anything. I noticed that it drops after "Checking serial number". I got my game through steam, can that be the problem?
Oh, also, I tried re-installing, regediting the serial number, etc etc. It accepts my serial number when it asks for it, the only problem that I have is that it just won't connect to any of the servers with any of the modules that I have installed.

No specific error message, nothing exeptional pops up in the console. I tried the "use_secure_connection = 0" stuff too, no change.
