I got it working for once. but no single player commands wont work, any idea how i can make it work? (i manually installed it, not the auto installer.)

Log error: Mod installed (in order) Forge GuiAPI Dzarks custom spawner single player commands. i was going to install the mo creatures mod but i wanted to make sure everything else worked before i installed it and when i did i got a "fatal error" mesage..
