Title: Can't Launch Tekkit Classic

Version: 3.1.2

OS: Windows Vista 32bit

Description of Problem:

I was trying to launch tekkit classic on the new BETA launcher (for the first time on this computer), it loaded for a bit, and then a message and a log showed up, so I can't launch tekkit classic anymore. Every time I try, the message shows up.

Error Messages:

Unexpected Error!

Error Log:

By "it loads for a bit", do you mean it downloads the modpacks and everything?
