Also, I would to know if there is a way to fix that in a existing world because you cant join the world anymore (after the "loading terrain" the game crashes again) and I have a server that I play with a friend and I want to keep playing :3

hm so depending on what crashes, you might be out of luck. I assume the block has been placed in the world, and is now erroring. Sadly I think the only thing you can do is open the world in mcedit and remove the block there. Then, add the registry name (problably something like "mekanism:wind_generator" ) to the blacklist.
