Analytics Edge is licensed by computer, so the add-in keeps track of the computer it is licensed for (even the free product is licensed). Sometimes a Windows Update or hardware change will mess up the license, and you will get an error saying “License issued to a different computer”.
For the free products (Basic Add-in and Free Google Analytics connector), upgrading to the latest release will usually fix the problem.
For other products, opening the License wizard will sometimes re-activate the licenses for the updated computer.
If none of that helps, then send a note to email@example.com, and I will fix the licenses for you.
