The protection key could not be found (hasp status 64).

When starting Pythagoras, you may see the message The protection key could not be found (hasp status 64).
This means the Sentinel License Service has detected a Cloned Sentinel SL storage. This error only affects software licenses stored locally on the computer. Changes caused by virtualisation software, such as Parallels updates, can invalidate that fingerprint and trigger a cloned license detection. 

The license itself is not lost, but it is temporarily blocked for safety reasons.
