There will be no official fix for the game keys, because that would mean making a new version of Vikingr for the new version of Warband without the WSE Loader. That would mean that features would be lost, which would mean its not really Vikingr anymore. Therefore, no new version and no CD Key fix. Not to mention that there are no 'official' developers for the mod anymore.
But all of that has been said in the forums already. Especially only one thread below this thread, named 'Vikingr 2.0'.
