Welcome to the community George!
It sounds like you're trying to import a license that is not available / has not first been exported.
If you wish to run the software on both machines and as you no longer have access to the previous license (broken laptop), you would simply need to proceed with the standard install and activation process. Should you run into any licensing issues at that point, please contact our License Assistance Team for direct support.
Here to help if additional clarification is needed, otherwise please accept as a solution so that others can benefit from this information.
