Okay I'm sorry because I know you guys probably get a lot of bug reports like this but none of them have solved my problem. Technic Launcher wont open at ALL. No logo, no nothing. I tried deleting the unnecessary files and the files I was asked to delete as well. I tried installing a new version of Java. Nothing worked. I know there's something I'm missing but I've trying everything I can think of. What am I doing wrong?
