validating purchase code....

The purchase code is already assigned to another domain name.

Your purchase code is tied to the domain name you used to validate it. This means if you update your domain name or push the project to another host, it will not work there.

To use this project on a new domain name, you will have to first invalidate it on the old domain before you can use on another domain.

Check the documentation that came with this project on what to do.
