I can't find the 'Sentinel Product Key' for my Gemalto entitlement. 

When attempting to activate an Entitlement you get the error;

System,Net.WebException: The remote server returned an error: (400)
Bad Request.
at System.Net.HttpWebRequest.GetResponse()
at HCADLicense,Form1.Iogin(String product_key)
at HCADLicense.Form1.btnAuthorize_Click(Object sender, EventArgs e)

When trying to transfer an Entitlement using the Hydratec Entitlement Transfer Utility ("C:\HES\Common\Entitlement Transfer\HydraEntitlementTransfer.exe") , after plugging in the USB to the "new" computer, you can't see a license to transfer.

The recipient does not show up the the window for licenses available to move (top right), but are visible in the bottom right window.

When attempting to activate an Entitlement you get the error;

System.Invalid.OperationException: Failed to generate Fingerprint
