I loaded a fresh jar and installed the 3 prerequisites. The game loads fine. When I put the IC2 jar in the mod folder and open the game, it crashes and I get this bug report. If I remove it, the game runs fine. Kinda confused cus I have never had this problem before. Any help would be appreciated as I didn't see anyone with the same bug.
