Technic launcher hates me! (I think)

Harry Williams · March 25, 2014

Now I'm no expert on Technic Pack, but I know something is amiss when I can't even load modpacks on Technic Launcher. When I try loading Tekkit, which I have had no problem with in the past, it makes it to the Java loading screen, then crashes before the menu is loaded and returns to the launcher, as it always does when it is closed or crashes. More frustrating yet, when I try to load B-Team, which I really want to play, it crashes before FML even starts up. I have copied the console text from launching B-Team that shows the problem so anyone who is experiencing a similar problem or knows what to do can have a look, and if it is further required I can get the console for Tekkit. I am so sorry that my first forum post (at least in a long time) has had to be negative, but I hope this can be solved soon.

I am a windows user, using the 1GB memory option, and the same issue occurs with both stable and beta builds. Launcher build 431
