You have added factorization to Tekkit, but how exactly? Have you installed a craftbukkit version in the server mod files? If you haven't got a fully compatible server mod of Factorization, it simply won't work.

This is an FML error. You have to wipe all FML files from your computer completely, delete the .techniclauncher folder as well as the server files, and then try again.
