Guild Wars 2

I bought the expansion today and I was hoping I would be able to use the new specialization in pvp , but it doesnt show as available in the pvp lobby. Must be a bug? How can I fix it?

yeah did that now , 1 mob disapeared and seemed like never came back . Reseted the instance and it worked ok now.

Atm im doing the story mod quests and im stuck at the dream of the pale tree of orr. I cant seem to finish the quest as the questgiver wont let me contenue. please help.
