I just finished downloading the update for PlayOnline and everything was going as per usual. PlayOnline closes and begins to reboot but then I get a window pop-up that says:

Error code = 20008017
Cannot move version update files.

I click ok, as that is the only option and then PlayOnline shuts down. I've tried again and again but this same problem just keeps happening. I really have no idea what this means but I get the feeling I'm going to have to go into the game files and actually move some stuff around. Any ideas?
