You are trying to play with tekkit lite (minecraft version: 1.4.7 and that has more/other mods) on a tekkit classic server (minecraft version: 1.2.5 that has less mods/other mods that tekkit lite has)

This is the link to the right server package that you are looking for:

Download the server.zip and delete all your world folders + any tekkit classic folders before applying this newer version on.
