So I started trying to build a pack and regardless of the mod that I put in, They all give the forge mod loader an exception error and that seems strange to me as i dont recall having that issue over a year ago.
I created a pack, chose 1.7.10, grabbed the latest forge that it gives me in the options, i have the latest java 64bit (220.127.116.11 i believe)
mods ive tried so far
portalgun - crashes, if turned off - loads fine
zelda skills -same thing for both results
enhanced portals 3 - same thing
even optifine wont work. it says its looking for jvm arguments but ive tried with it jmvs enabled and disabled and get same results
