Well, the same old thing. Vanilla Runs, but Forge Profiles won't.
I do have the latest Forge installed, and also a bunch of older ones. Not a single one works.
I did downgrade Java from 8 to 7 and still nothing.
I did remove my entire .minecraft folder and installed it anew.
I did create a new system variable to up the maxium heap of Java memory.
...and I did read the EAQ and found nothing useful/that I haven't tried.
also, there're no logs. seriously. my latest log after an unsuccessful launch just reads:
[09:38:33] [Client thread/INFO]: Setting user: GabiLua
