This is the second time I've seen this error. I had the other guy remove NEI from the mod folder and he said it didn't work. Try that and let me know.

Are you OP or anything?

If the server's otherwise running fine, and other people can join, reinstall your Tekkit client. If it does this to everyone, reinstall the server.
