After updating the MassCore - RTX engine, your RTX dongle is no longer recognized, and therefore your MassCore is not authorized.
The Led on the RTX Hasp dongle stays off.
This does not affect the Merging - Safenet dongle (all your authorizations are valid in the MT Security panel).


You have probably installed a driver for the RTX Hasp dongle manually, which is now included in MassCore installer, but the two versions cannot coexist.
