Nevermind, i selected the wrong build. Derp..

I set up a tekkit server today. My friends fixed this error happening to them by manually selecting the build and forcing an update. This did not work for me. They were able to join my server, and I get this error. They said the at the bottom of the main minecraft screen it will say that it loaded about 36 mods or so. Mine doesn't say that. I have tried many many times to redo everything, and do exactly as they did with no luck! Please help!
