Looks like you have an ID conflict. This has happened to me before, resetting the modpack usually does the job. If that doesn't work, try backing up the config files for the pack (located at your %appdata%/.technic/tekkit/config directory), deleting them and running the mod again. If THAT doesn't work, just redownload it.
