I can't log into Green, Teal or Blue

[MalvieSalty]

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.
