OldCandyMan

I am currently stuck at the part in the Highland Necropoplis where you are to give Old Man Cho the container. Can't seem to do the windwalk that gets me up to him. The one where you run up the side of a building. Would the game fail if I could not complete this task?

I am unable to login. The launcher returns with a red bar across the top saying "Failed to log in. Please try again later. (0)" . Login server down?
