Description of Problem:

When I try connecting to a tekkit server I was able to connect to before it gives me an error, and won't let me connect. I can connect to other tekkit servers but just not this one.

This server requires you to have the following mods:

mod_TubeStuff 49.1.1

Mine does the same thing but i have 5-10 mods that it says it for

That means the server's still running 3.1.1, and hasn't upgraded to 3.1.2 yet.
