Tekkit crashing every time I log in after update

[Gemma Penhorwood]

Title: Tekkit crashing every time I log in after update

Version: 3.1.2

OS: Mac OS X 10.6.8

Java Version: 1.6.0_37

Description of Problem:

I updated the technic launcher and now it crashes every time I log in. I've tried re downloading it and whenever I don't ask for the update it can run things properly, but can't go on any new tekkit servers because it doesn't have the updated mods. BUT, if I do update, it tells me the version is not 2.1.1 (I only chose it because I had to pick one, it's required) it is actually 1.0.2.0 ... which is weird, because I downloaded the latest one 3.1.2. I think two different mods are trying to occupy the same slot, but I'm not sure. Help me please?? D:

Error Messages:

This appears after the Mojang start up screen (a screenshot of the Tekkit launcher)
