although a couple of you are having a dif problem than me w/ the load loose files box, changing the line in my *.ini file didnt allow me to click on data files option :( i still have no fix for my particular problem. If you are still having troubles with the Data Files thing, i just figured out you don't have to change the SkyrimPrefs.ini that's in the game folder, but the one that's in C:\Users\****\Documents\My Games\Skyrim. This ini didn't have the line that you suggested, adding it fixed the problem. thanks too someone else that posted this and it worked for me try it works 100%
