Hello,
I’ve checked your Purchase Code and it is registered in our DB and you created account on our site using your purchase code, but Envato doesn’t verify it.
Seems Envato is experiencing some problems with their API to validate purchase codes. Unfortunately, this is outside of our control as it’s related to their servers. We recommend you retry over the next hours, once their API is back up it will validate fine.
Also, please contact Envato support about this.
If there is anything in the meantime I can help you with let me know.
Regards,
Rose Tyler.
