I recently made a custom modpack and I uploaded it to the Technic website then i downloaded it in the launcher but when I went to play it, it would load the modpack and then close the launcher so that it could load minecraft but before minecraft even came up it would immediately reopen the launcher and would never load minecraft. I have looked at the version of forge and the version of minecraft i specified on the Technic website and they appear to be the same (1.7.10). I have all the same version of mods as I do forge and minecraft (1.7.10). I put the error log below I can kind of tell what it means but I am not good at reading code. I know it has something to do with forge mod loader but i have no idea of where to go to fix the issue. I have reinstalled forge and it still does not work. The tutorial that I watched on making the modpack told me to rename forge to "modpack" I dont Know if that is the issue or not but if anyone could help it would be very nice of you.
