Hello,
Apologies for the delay in this answer. For some reason, you were not re-directed to the new BoldGrid Support page when you asked your question. The issue has since been resolved and questions that were not supposed to go this older system are being addressed. So, again, our sincere apologies for the confusion.
Licensing messages typically indicate that the license has either not been applied or it is not been recognized. One of the ways to address it is to remove the software and then re-install it. You will see the license requested when you load the BoldGrid Inspirations plugin. If you wish for the BoldGrid support team to look a the issue directly, then, please re-submit the question to the new support page along with your domain information so that the key in question can be found.
If you have any further questions or comments, please let us know
