cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: net/minecraft/client/entity/EntityClientPlayerMP

I see an error there, Maybe the client, something about a class not being found....

I'm having the same error. It worked fine for me before, and then it suddenly broke.

By looking at the log it seems the block "Compressed Redstone" is causing the error. If you have any Events then try to remove/change them. If it still doesn't work then try removing and recreating the whole block or if there's no other choice, you might just have to completely remove the block.

Also if this still doesn't fix the error, then try repeating the steps on the last item you created before it stopped working.
