I had that issue too, after trying for a while I contacted support here and sent them a screenshot with the ouput of lspci.

The following day I got a new code that didn't requiere using AMD PVT.

Hope this helps

I had that issue too, apparently the vendor gave me a code for the wrong piece of hardware, either way amd support helped me get the correct code that verified properly.

It didn't work for me either. I contacted their support and they asked for a picture of the serial number on the box, a copy of the invoice and the code. They got it verified a few hours later.

What does that script even do, other than running lspci and, presumably, misreading the output? Did anyone read it?

Apparently it requires some kind of account.
