 8. Save the hosts file. Go back into terminal and type dscacheutil -flushcache. quit terminal.
 9. Open PS and it will launch a product activation thing as well. Now all the other torrent instructions said something about going to PS help menu and clicking "deactivate", but for me it was always greyed out.
 10. Input this serial into the product activation window - 1325-0621-9125-0765-3648-0614
 11. That should be it.
