1.8? Any particular reason for that? I thought it was still in the snapshot stage, and I'm quite frankly surprised that 1.6.4 would be able to load a world produced with it regardless as to what mods you're using.

Can you try the same steps using a world generated by MC 1.6?

Option 1: Reinstall Forge Vanilla Server

Option 2: Delete current /mods/ folder in server directory and re-install the latest ComputerCraft

Did both, didn't seem to work.

EDIT: working now, I think it was a building someone made with lots of disk drives that was lagging the server.

Maybe that giant "database" at PlokeLabs?
