I installed the mod Heart of the Dead today, and it overwrote a bunch of videos in the C:\Program Files\Steam\steamapps\common\oblivion\Data\Video folder. Now when I run the game, it crashes after I click "Play Game." I've disabled HoD in the Data Files but obviously that won't help with the videos that were overwritten.
Any advice? I'm running the Steam version so I don't have a game disc I can pull the originals from.
