So, I've been playing Skyrim for about three weeks now, even though I had known a lot of information on the game prior to playing. I've reached level 36, I'm a nord with full Daedric Armour and a Daedric Sword + Bow. I made both my armour and weapons legendary, so it's extremely difficult for me to take damage, even though I can deal a lot. Or at least, it was difficult.

I was doing a quest where Mercer and I look for Karliah in underground ruins. I was going through the ruins, EASILY killing all the Draugrs that got in my way, even Deathlords and Scourges, but I got stuck a little far into the quest, so I left it for a moment. I went around Skyrim, and I decided to go back to the quest. When I returned, I went to kill the Draugrs again, but I was doing, at the maximum, eight damage per swing with my legendary Daedric sword that usually does sixty damage. The Draugrs, on the other hand, were dealing INSANE amounts of damage. I mean, with my armour rating (400 or so, I believe), they had to be doing 100 damage per swing. I tried reloading the quest, expecting the problem to just be a bug/glitch, but after two reloads with no success, I realized something was really wrong.

I removed the game, cleaned the disc, and tried again, THREE TIMES. It didn't work. I turned off the PS3 three times, and once again, I had no results.

So, I had an idea. I thought that maybe if I created another user and tried restarting the game, then maybe it would be fixed. It would've svcked to restart, but at least I wouldn't have to deal with that damned bug. So, as soon as I picked up a weapon in the Helgen Keep, I attacked the Imperial Captain. Almost NO damage, and [censored] two-hitted me.

I'm not sure if this a software glitch within the game, or a problem with the disc (which is what I'm assuming, considering the fact that the problem existed on both users), but either way I need as much help as I can get. My level 35 Nord is the best character I've got, and it's the farthest I've gotten! I don't want to lose that

Any help/advice would be greatly appreciated! If you've experienced the same problem and fixed it, please tell me how! Thanks!!!
