bug: crash when clicking on any button in a GUI

  • I was starting up minecraft to enjoy some awesome IC2, but suddenly a crash appeared! I believe this crash manifests itself when a GUI button on the main screen (or possibly any other screen) is pressed (the error log is below). I attempted to find the exact mod versions I was using, only to find that the "mods" button crashes it in addition to the "singleplayer" button. Interestingly enough, before this bug started, the same crash would happen as I tried to change my new world from creative to survival (on the world creation screen). My mods: FML/Forge: latest recommended build, IC2 v1.106. I think. Also, when I first started it up, it gave me a crash that I fixed by turning "enable sounds" to false. (you know, in the config). I may have installed it wrong, but I don't think so. (sorry, I couldn't figure how to get the crash report into separate lines in the code box)
