well for my problem, i just had to restore the preferences to default, turn the audio and visual effects on and back to normal. and then ingame i had to leave the area and return for the scripts to start working again.
i looked at older topics and it seems that others have had this problem, but theirs included the game unregistering, mine didnt.
NOTE: a more serious problem occurs from this. i has finishing up the Hunting Bennhold quest when i had the problem occur. so when i left and returned no one was left in the camp, all their items were laying as if killed, however there was no way to receive credit for this quest.
