If you are using the Technic Launcher, you should go to the folder. Search %appdata%. Then look for .techniclauncher. Go inside, look for a folder called tekkit. Backup anything you need (maps, screenshots, etc.) Delet the entire tekkit folder. Then run the Technic Launcher again and reinstall tekkit.
