I cannot launch third party packs. When i click on the launch button, if it needs to update or download it does that, but then the ftb launcher closes and minecraft doesn't start. Official FTB modpacks work, jjust not third party ones.
I downloaded all the files correctly, and when I launch the serverstart.bat it will open up the white console (after the black one) and then it will give me this error:
---- Minecraft Crash Report ----
// Ouch. That hurt :(
