My developer tells me he is unable to register Pro with the license key I provided to him

My developer tells me he is unable to register Pro with the license key I provided to him. He says he gets a message reporting another theme is in use with the key.

Here’s what he reports:
Encountered a problem.
Your code is valid but looks like it has already been used on another site. You can revoke and re-assign within your Themeco account.

When I look at licenses on your site, I see Two Pro licenses: one for production (registered and in use). Another (it says converted from ThemeForest, and that nothing is registered).

Do I need to purchase another license? What’s the story?

Hi @bmccallion,

Thanks for writing in.

The error shows that you have used the code in other site. To use in on the new site, please try to revoke the previous license where you used it then revalidate it to the new site.

Let us know how it goes.

Thanks.
