[game crashes on pressing alt]

The alt key pauses the game or something. I've also had this happen.

[[Logs included] Fixing Yogbox 1.2.5]

Couldn't find another to place to post this but here's the deal.

Im trying to get the latest version of Thaumcraft 2 on Yogbox, but this requires the use of Yogbox 1.2.5, which of course, is broken. Now im working on finding out what the hell is causing 1.2.5 to crash. Since I barely understand how Java works at all, I'll leave a log file here for you guys to figure out. I'll cut out information i find useless to reduce the size of this post.

By the way, im using Windows 8.1 and the latest version of Java as of now. 4GB RAM and a penti.
