I am having the same issue, I've tried a couple of different things, but nothings helps. On one attempt I was able to get into the game and log in, but as soon as I was able to see my character standing in Viridian Forest it froze completely. I am not able to close PRO down of even click on anything, i can bring the Task Manager up but am unable to click an application to close. I guess on the bright side of this problem is that it is a known issue for a large number of people so hopefully it will be fixed soon.
