Well, it will sometimes run and sometimes not. It may run for me in admin mode, and other times it does not. The behavior is not consistent, which leads me to believe that their login or backend servers are not all at the same patch/build level, either. I don't know, but to say it is frustrating is a complete understatement. I can't believe they haven't rolled back, yet.
At some point, they need to pull the plug, roll back, and resolve it completely.
Although it is simple enough, I'm NOT going to start jacking around with client folders, running repairs, and tweaking start-ups. For all I know, those actions will complicate recovery. I'm fine with waiting for something to get fixed before release (i.e. wvw alliance beta was pulled). I'm NOT fine with having to deal with a broken system, when we all know the last build was functional.
ROLL IT BACK! RIGHT MEOW!
