I'm trapped!

I think because my level was high enough i was able to pass into the next area but i didn't finish the mission before it. I ended up completing that mission but had to go back to beat the one before. You following do far? Okay, good because now I can't redo the mission I already beat and can't pass into the next area. The game won't let me. Now what? HELP!

If this is the Ambassador mission then good luck...I've had the problem with getting through the portal too soon and now it shows I only healed 1 guard when I actually healed all 3. I have had no luck getting this fixed since it happened June 21.

June 27 and still no fix for me. They announced a fix but my char (MissMurder) still doesn't work.
