I am with him in this game and here are my info
If you need anything else just let us know, we are really having a blast with the game and would like to be able to finish it all together 
none of us are the host, we will have him post everything here real soon.
Even with the patch nothing happens when I enter the boss arena, we are in combat cause our stamina drops and there are corpse of big bats (first wave before boss) but nothing else.
