Logging onto a server crashes the game

Title: Logging onto a server crashes the game

Version: 3.1.1

OS: Windows 7 64-bit

Java Version: 1.7.0_05

Description of Problem:

After logging into tekkit without problems and starting the minecraft client, i go to a friends' server, which i had no problems logging into up till an hour ago, it says:

Logging in (with a dirt screen)

then just a dirt screen for a second or 2

then another split second of Loggin in (with a dirt screen)

then another slightly darker dirtscreen

then white screen and i have to quit the client.

It started when i pressed middle mouse button on nicolite in his quarry to show him that they weren't diamond (in creative mode). as soon as i pressed it, the game went to a white screen and now i can't log onto his server anymore.

i deleted and redownloaded both my .minecraft and .techniclauncher folders, which didn't help.

my friend removed me from the playerlist in his server folder, to get me to respawn at the original spawnpoint, which didn't help either.

single player works fine.

any other solutions/suggestions?

If deleting your player.dat file, which contains your inventory, didn't work, you'll probably need to reinstall your copy of Tekkit. Save your waypoints if you want them.
