I’m sorry about this. Earlier today the Envato purchase API was down, which prevents us from verifying new licenses. We’ve been informed by Envato’s engineers that the problem has been corrected. You should be able to verify your purchase code now.
You should be able to validate it by now. If still experiencing any issues, please login to your account, https://community.theme.co/users/pepnet/licenses/ and revoke that license. Please generate a new one and try to validate your site again.
