Activation key error

I recently bought a one time subscription and while activating it says - You have entered an upgrade key. Please confirm it with a key from the previous version. Please, is the key from the previous version free, if yes, how do I get this key? Thanks

 

Hello, did you use the Parallels Desktop before?
If not you need to purchase a full version.
Please provide us with the purchase order number and we will proceed the refund.

 

To be clear, what exactly did I purchase? Maria@parallels Please proceed with the refund this doesn't feel right. The purchase order number is A0033981622

 

According to the message you received, you've purchased an upgrade version, but if you didn't use Parallels Desktop before you need full version of Parallels Desktop.
Did you purchase the license from parallels.com?

I'm having the same problem RaquelR is having; migrated Macs, and now despite never having had multiple Parallels accounts it assures me my key is "attached to another account" and I can't activate P15.
