Hi Debbie, I should have emailed in again as I have managed to get around this issue. It seems like it was being caused indirectly by me not properly set up the owner key.
Sorry for not stating as much. Would you be willing to help me with a different issue I've run into while trying use unseal? If you wouldn't mind I can post the code as well as the different outputs I've been getting from it?
