I will launch voltz via the technic launcher and as it starts to launch it crashes. I opened up the console and read through it to see any problems and didn't find any other than right at the end of when it crashes.
I also try to launch minecraft vanilla on the 1.3.8 launcher and version 1.7.4 of minecraft. I will launch that and be able to get into the screen where you can select multiplayer or singleplayer and I try to launch a singleplayer or multiplayer server and it crashes. After that I went to the development console to look for anything wrong but couldn't find anything that could be wrong except for what is below.

If anyone knows how to fix this please reply to this topic. I could really use some help because this has been happening for a month now.
