Guild Wars 2

While attempting to begin Twilight Arbor dungeon in story mode.. my team, and pretty much every other team was faced with a large problem. Everyone had difficulties actually entering the dungeon. The solution for some and not others was to log off and log back on to get the pop up asking if you would like to enter the dungeon. However, if you declined the first pop up, then any other attempt would fail, unless you logged back out again. Hope this gets addressed asap.
Thanks!

This is happening with Ascalonian Catacombs as well.
