Forum:Desperately in Need of Knoxx Help

Okay, I've been asking around on a bunch of forums and have had no luck thus far, so why not try here? Well, I'm stuck in the General Knoxx DLC. I exited after going into the elevator, and both the objectives for the Armory Assault quest are checked. Problem is, when I go back, there is a door that you can't pass anymore, meaning I can't turn in the quest.

So. I need your help. If you have a character that has started the DLC, preferably closer to fighting General Knoxx, I need an invite to a game with someone who hasn't completed the mission so that I can complete it normally with them, thus finally finishing my mission so that I can continue to play the DLC.

My XBL Gamertag is DoomBunnies, please contact me.

I just feel pretty bad because I've already lost my character once to a glitch that made my file !Corrupt or whatever, so I've had to start all over once.

Public games don't show hosts above level 50, which means I can't find too many people past the beginning because the DLC allows for leveling past 50.

Once again, my XBL Gamertag is DoomBunnies. I hope someone can help me.
