I can't log into Green, Teal or Blue
 

Basically I got the game working to the point that I can enter the Red server but I can't enter any of the other servers.

As soon as I click enter world. It freezes for a few mins then says the server is not responding. It's getting to the point where I can't be bothered with all this as I just wanted to try the classic stuff.

Anyway if anyone knows a fix do let me know as I really really need to know.

I have no idea but maybe try turning off any firewalls and antivirus? Also (and sorry if this is against some kind of rule) maybe try some VPN to see if it's something wrong with your specific IP (e.g. AVG has a nice trial VPN and there are some free ones out there)
