Minecraft loads fine when I add the file to my .jar - Forge recongizes the mod as mod_test.
But when I try to add a mod that gives the game more blocks (I was already at the 256 limit before installing, I receive this error
Its pretty much the same error I've been getting when I try to add mods that add blocks. The mod I'm adding is called Netherrocks, and its the Client Forge version. All the mods I'm using are compatible with Forge. The current forge version that I'm using is 3.2.5.120.
