Go into .Techniclauncher, then go to the Tekkit folder, then go into the Mods folder. You have two copies of the same mod in there, the simple fix is to delete the older mod. If their the same just delete one, and scour the rest of the folder for any more copied mods. If you leave doubles it will cause similar crashes.
