Ok To start things off I will say that technic has worked for me before but I took a break and dont have a real date of when it stopped working.
The Problem
The Technic launcher works fine and normally, it has no out of the ordinary errors, it installs mod-packs, looks fine, all settings are good, and it seems to launch mod-packs when I tell it to. However after a couple seconds or minutes The launcher re-appears as if i didn't run a mod-pack. the console doesn't contain any red errors but it does contain "Current Language: ~~ERROR~~ NullPointerException: null" and "penGL: ~~ERROR~~ RuntimeException: No OpenGL context found in the current thread." My system details according to technic are "-- System Details --
