Work in 911 Center. Use Multiplicity on workstations to copy and paste between 2 PC's at each console. The secondary PC had harddrive failure so have temp replacement. Tried removing 2ndary and then finally uninstalled multiplicity from both secondary and primary. The employee who has left the company had the email going to his account. I got into the stardock site and changed the email to mine, but I do not get an email from stardock (even in spam) so I can install it again using my email. I can't get any further with the key not matching the email address.
