Do you need this? If so, perhaps your internal/external IP has changed and this was never updated.

Vexyl, you are AWESOME. Thank you, that was the problem all along.

Now, I can login from the same machine the server is running on. My dad however, who used to play with me and lives across the country, cannot login.

He can't get past the login screen. It just tells him a connection to the server cannot be reached.
