EDIT: Herp derp. I didn't realize SkyrimPrefs.ini was in TWO places. For those who are still having problems, make sure you're editting the SkryimPrefs.ini in your User\[Account name]\Documents\My Games\Skrim folder. Works perfectly now. First I still couldn't find the second one. I just installed skyrim again. I was searching for the save files from my first version, and there I read: SkyrimPrefs. OMG. I found it on my NAS. I don't know if anyone else got that, but you can open your start menu, and type in search: save. Then you click on one of your savefiles and look in what map it is. I hope this works for you guys. (P.S. sorry for my english. I'm from the Netherlands. XD)
