Hello,
First I would like to thank you guys for making minecraft forge, it has kept people like me from spending days writing code to get a single mod to work.
Second, I have been having an issue where I have been trying to mod the vanilla minecraft in the technic launcher. Vanilla itself works perfectly fine until I take minecraft forge and install it into the .jar using 7zip. I made sure to remove all mods/ saves from those folders and delete the META-inf folder before I install minecraft forge. What happens is I start up the technic launcher, select vanilla, login and the it says checking for minecraft update, then vanilla opens and freezes at a white screen while Java pops up a blank window that has Hello across the top bar next to the java symbol. I got Forge 3.3.7 to work with 1.2.5 but I cannot seem to get Forge 4.0.0.241 universal to work. under the spoiler I am posting what I think is an error report, but I can't be sure because I do not speak computer. and I have looked and as far as I kow this has not been attempted before.
