Title: Unknown login error tekkit 1.5.2

Version: 1_0_3

OS: Windows 8, 64 bit

Java Version: 1.7.0_25-b17

Description of Problem:

Hello,

I have a problem with getting onto my tekkit server. Whenever I log into the server with my account, minecraft crashes with the following error report. I have tried to log on with different computers and I have the same problem. However, when a friend logs onto the same server with the same computer they get on without trouble. I'm using the tekkit 1.5.2 server.

Also, I don't have this problem when I try to play on singleplayer.

Ignore this, I accidentally posted this before I found the edit button and can't find the delete button.

did it resolve itself or did you do something?

Not really, I just logged in one time to this message. I'm not really sure when it started and it was working fine before the message.
