Before diving into deep system settings, try these "low-hanging fruit" solutions:
If your computer has an older driver installed for a Sentinel HL key, but you are plugging in a newer Sentinel Pro key (or vice versa), the software may attempt to communicate using the wrong protocol, resulting in a mismatch error. The Hardware Information Does Not Match With Your Dongle
Sometimes, despite your best efforts, the error persists. When you open a support ticket, do not just write “Dongle doesn’t work.” Provide these three critical pieces of information to get a fast resolution: Before diving into deep system settings, try these

The bridge between your OS and the USB hardware is broken.
Occasionally, security software blocks the communication between the program and the USB port. Try disabling your antivirus temporarily to see if the error clears. 5. Hardware Damage
