Cryght

I've tried searching, the only topics i've found showed no solution.. I was on a Tekkit server earlier today, and as I try getting on now this shows up, and only gives me offline mode to do.. I do not know what could be causing the issue, but i'd apreciate the help.

is there a fix for this? its getting annoying with going on servers and people crash it due to this glitch

yet all the mods will need to update to 1.2..
