Playing Skyrim on Xbox. @LordBrother - It didn't work for me

That quest that you were talking about, where you killed the dragon at Northwind Summit, learned a word, then were able to open the door at Valthume... was that a bounty quest given to you by the Inn keeper in Ivarstead? I ask because I went to him, hoping to do this same quest and therefore, be able to finish the quest at Valthume. Instead, he gave me the same quest, only I had to kill a dragon in a different location. (This is because I had already been to Northwind Summit, killed the dragon and learned the word). So I went to this other location, killed the dragon, learned the word, but it didn't change anything at Valthume.
I tried everything... reloading previous saves, returning to that Iron door later on in the game, deleting/installing the game from my hard drive, etc... Nothing!
Does anyone know anything else I can try? Is this something that will be fixed in a future patch?
This is a pretty f'd up bug. It keeps an entire quest from being completed, prevents the player from learning a Word, and prevents the player from getting all 8 Masks! I was trying to collect them all. This would have been #7. Bravo, developers. I really hope a fix is in the works for this problem. Otherwise, it's like I bought something that doesnt work the way it should. Refund? lol
