Hi Frank,
Thanks for raising the concern.
The error appearing is not as per the product behavior since we can re-host a license back to its original machine. We need your cooperation to get below details for narrow downing the root cause.
1- The error screenshot with the message at the time of rehost.
2- Confirm the steps taken to rehost the license back.
3- Confirm at which point does the error appears.
Looking forward to your reply.
Thanks & Regards,
Parth Kaushik
