So, Having followed these steps, I put in the wrong license key (because the pdf guide doesn’t mention where to find the license key) and ended up putting the serial number for the purchase.
Now every time I try put in the Correct License key, it still updates with the old one.
How do I rectify this?
(Note for anyone having similar issues, your license key can be found on your profile when you log into prodesigns.com, and NOT on your invoice, don’t repeat my mistakes)
