Sorry your having trouble jumping on our server
![cry :cry](./images/smilies/cry.png)
A couple ideas for you:
When entering the IP, try dropping the ":7777" part and see if that helps.
Add {ESC}* to your buddies list. This will show you where every ESC member is playing, chances are good that at least one will be on our server.
Please let us know if you still can not connect.
Cheers, Lager
