I deleted one of the Skyrim updates and then reinstalled it to see if it would fix any of the bugs and then I noticed that for some reason all the DLC I installed(Dawnguard, Hearthfire and Dragonborn) was all gone! Did I screw myself over? Was there a way to have backed up all my data before I did this? I hope I don't have to start all over because if I do, I'm gonna just throw in the towel. I spent dozens of hours on all this.
