Tried to upgrade from trial. I failed somehow. Did I do anything wrong?

I am awaiting a response from Unraid support. Thought I'd ask here and make sure that I didn't miss a step.

Had my trial running on the latest version. Backed up the USB key to my Windows machine. Used USB Creator to make the new key, a fat32 formatted 64gb MicroSD card inside a USB reader, restoring from the backup. When I start the server, it mentions the key mismatch as expected.

Tried to purchase a new key through the Purchase Key link in the GUI. For whatever reason, the checkout was not available. As in I'd click on checkout and nothing would happen. Turned off ublock, turned off my VPN, nothing. Wouldn't let me check out.

Replace key does not work. Just comes back with an error. I believe this is because you cannot transfer trial keys?

Purchased a new key by just going to the unraid website. Try Replace Key. Website says USB device already has a key or is blacklisted. Both the reader and card were purchased new.

Redeem Activation code also mentions that USB device already has a key or is blacklisted.

Did I muck something up or have I encountered an unexpected error?

--edit--

Unraid support was very helpful in diagnosing the issue as a cheap USB reader with a non unique USB GUID. Thanks for those that offered their advice.
