I recently had to reinstall my Skyrim and update it again bacause it refused to run for some unknown reason.
I took out my saves folder and put it back in after I updated.
Could this cause my save files to not be able to load?

And there is another thing, i can′t get my Data Files enabled on the start-up screen even when adjusting the Skyrimprefs.ini.
I did get it up before I reinstalled but then the problem was it wouldn′t find Dawnguard of Heartfire, I had both of them in my data files.
After a while ( don′t ask me why ) it finaly did but then it crashed seconds after startup. With or without the DLC′s enabled.

I have tried a lot of different things I found on the internet and am getting pretty sick of this.
I allready completely removed and reinstalled Skyrim twice in the past few days.
So it cost me about 16gig bandwith allready and it′s still not working.

Any help will be greattly apreciated.
