I had unity install on my PC computer running Vista, no problems UNTIL my computer crashed and I had to reinstall Unity. I uninstalle unity, and as directed deleted the Pace Anit-Piracy/license files. restarted and reinstalled, but now I cannot register...it just keeps saying "waiting for server response". Anyone have this problem and know a solution? Its very frustrating, I have not been able to work for two weeks and tech support takes days to respond.
