OpenModsLib crash transformers This was a line that i can't really undesrtand, but try removing the OpenMods, like openblocks ... I am not really sure if that's the case, but something else you have to make sure is that the CoreMods (example: CodeChickenCore,Aroma1997Core) are the newest versions. What i mean is that you cannot run a new version of the mod with the older version of the library files. By the way, do you get the error or just they? Make sure you give them your exact copy of "mods" folder in your minecraft folder. One last thing is to remove MagriCulture. These are the only suggestions that i can make you. If none of these works then i am sorry but i cannot really help you.
