it used to work, but not whenever i open hexxit( which is the only mod pack with this problem) it loads the mojang loading screen, then shows me this:
Forge Mod Loader has found a problem with your minecraft installation
You have mod sources that are duplicate within your system
Mod Id : File name
hexxitgear : HexxitGear-1.0-22...jar
Hexxitgear : HexxitGear-1.0-23..jar
Help is appreciated, thanks.
