Fairyy~:
Perhaps hold off a bit on trying to update/repair it ...I was on IRC last evening, and I believe there's a problem with one of the latest builds of DX ...whereas it's not saving info, and/or changes to same.
RomanDA can tell you all about it ....hey Dave?

Stardock's crew are aware of the problem ...though I'm not sure if your's is related.
Good luck though. Hope you get it sorted.
