Using the exact same files both client and server side I get this error when trying to connect to the server itself. I'm using your latest build: 4.4.7 build #46 Base, Compact, Integration, Lighting, Mechanical, and World. I've tried checking and re-downloading the files just in case but that hasn't done anything.

Nevermind...found out the problem was the download itself to the client. It wasn't recognizing the new file and kept the old version of Mechanical.
