I've been trying to troubleshoot this problem for almost half a year now, boredom has driven me to the edge. Modpacks used to load just fine, but one night I boot up Twitch and I get this message:
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0
Error: Could not find or load main class na
From what I've read on this forum and other forums, other people have gotten the first bit of that error, but I have yet to find an instance of the second bit. I've tried nearly everything I can think of: reinstalling, messing with settings, downloading it on a new OS, and more solutions I don't even recall. Twitch tech support has been pretty unhelpful (can't fault them for it, though). This is the last bit of the log, when things go wrong:
