vanquish is right, stop being so arrogant and move on
Okay, vanquish just earned himself a timeout for being a bossy little know-it-all and swearing.
MagicLauncher reads the mods and the code they modify, and will return errors if they overwrite each other. Zombe's usually spews errors at me and requires a "Forge Fix" which overwrites both forge and Zombes modifications. MagicLauncher is not the issue, but odds are there is an incompatibility somewhere. the best method is to disable all the mods and activate them one-by-one until you find the error.
I did, Forge is the only thing that bothers OF.
Are you using standart version of OptiFine?
If not try using the standart one.MC forge and optifine don't overwrite same classes,magic launcher would detect that and the error would be like "method not found exception".
