Every time I go to run my tekkit (or tekkitmain as some may call it) a window comes up saying "FML is setting up your minecraft environment". I know this is a normal process but it's what happens afterward that is the problem. Once that window closes, my tekkit stays at a white screen for a second or two and then crashes. I have the techniclauncher console running and I've noticed that it crashes a few lines after it says "27 achievements" if this helps anyone. I have tried deleting the folder that the content is contained in, I've tried redownloading the launcher, I've tried increasing PermGen size and allocated more memory, and now I'm out of ideas and need help. I'm currently running mac OS X 10.8.3 with Java 7, latest update and everything else on my computer is up to date too. If there is any help that can be given, including that of things that work on windows, I would greatly appreciate it.
