I recently have had this error message pop up "Activation was not successful. Please try again after rebooting your computer. If this persists, you may have to reinstall the program". If I try again RIGHT after the message, PPRO 1.5 starts fine. This message seemed to appear after installing Zone Alarm Security Suite, but that may just be a coincidence. I have all of the program executables given rights to my "trusted" and "internet" zones, so I do not see how this can be a problem with the firewall.
Any suggestions?
