Re: Server loading error

I fixed the problem. When the update is run on our hosting service it did not delete the Buildcraft, Config, Mods, and Redpower folders. I did a fresh install of 2.1.1 and stopped the server. Deleted those four folders and ran the update. Restarted the server and we were good to go.
