I purchased the pro version a few years ago, but cant upgrade

I purchased the original A* project pro some years ago. It’s now deprecated version 3.8.6. Should I be able to upgrade to the latest version, or do I need to purchase again?

I can’t find the original license email from Unity, but I can see the asset in my Asset Store list of assets.

Thank you.


Version 4 was a paid upgrade. However, if you use the same asset store account, you should get an automatic 50% discount on the upgrade (or 100% discount if you bought it very near to when version 4 was released). Try to add it to your cart, and the discount should automatically apply.
