Sentinel Superpro BSOD Windows 8.1 x64 Embedded

We are using Sentinel Superpro keys, and when using it with a new PC, the PC always crash.

Error says: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (SNTUSB64.SYS)

The crash happens when I attach the USB key to any of the USB plugs. If I remove the Sentinel driver the PC works fine, the USB plugs are working with Pen-drives, and mouse.

PC will not start correctly until the key is plugged into the USB.

I tried the Sentinel driver 7.5.7 first, then tried the 7.6.6, the error is the same. Tried with another older key, the PC crashes with that also, and tested both keys in another machine, where both work fine.

Windows 8.1 has the latest updates up to yesterday.

Any help would be appreciated.
