Serial Number already in use

A tip for the future: if using old serial-based software, you can only deactivate from the machine where it's installed. If you decommission the machine or it fails, you have to go through this rigmarole. This was resolved for the subscription-based apps that replace them at the high end. Elements apps still use the old model.

BE SURE TO ONLY ASK FOR ACTIVATION SUPPORT TO ADJUST YOUR ACTIVATION COUNT
You may need to PERSIST or TRY AGAIN to find a support agent with more experience
