Hi @dickheadfred,
Thanks for reaching out to let us know. We use Envato’s API to check if codes are tied to a valid X purchase. When verified, we add them to your Themeco account.
I’ve manually checked this code with their API, from what I can tell it isn’t a valid X purchase code. To be honest, I’m not sure why this would happen. It could be that after you purchased X, the code wasn’t properly stored in their system alongside your purchase.
I hate to ask you to do this, but could you please reach back out to Envato and let them know we have confirmed the code to be invalid? I’ve included a screenshot in a secure note with the results of trying to test the code with their API tool.
If you’d like us to try one more time before that you could send us the PDF license certificate. I don’t think it would yield a different result, but in the off chance there’s a typo in the key we could try copying from that document as well. We’re committed to helping you get this figured out.
