OK, I was having the same type of freezing issues people have been talking about here and elsewhere for Fallout 3 GOTY and so I followed the suggestions of deleting the game data (not the saved data) as stated to fix the problems, problem is, now the game won't load when I insert the disk, just a blank screen. Same goes for Oblivion, but I didn't do anything with the data for that game, just Fallout.

Can anyone help?
Thanks
