Locked out of plug-ins

I haven’t used them in a while, and now I’m locked out of at least two Profactions plugins.
I originally purchased the plugins for a different computer, though I’ve been on this computer for a year.
At least two Profactions plugins don’t “recognize” I’ve already entered codes and won’t function unless I re-enter. Then I receive a message I’ve already received two codes, and I’m locked out unless I re-purchase.
The creator’s nation is at war so I can’t reach.
Is there a way to get the plugins to recognize codes I’ve already entered?
Thanks.

You will need to purchase it again. It sounds like it’s a new end-product.
