| not to bump an old thread, but i found this post in my search for a solution to the same problem, so in the interests of posterity...
i had the same thing happen. i alt-tabbed from IWD to something else right after auto-saving and the whole thing actually rebooted. after that, whenever i would try to load a game from the main menu it would reboot the entire system. i tried starting a new game and then loading, at which time it crashed to the desktop with the error message you describe.
i re-installed, messed with the graphics settings, all to no avail. increasingly desperate, i thought to remove the auto-save from the save game directory.
works fine now. woo. save file must have gotten corrupted when it rebooted, although i still have no idea why it crashed in the first place.
