USB Hardware Key (Sentinel Dongle)
From Zenitel Wiki
If you get an error message "SuperPro initialization failed" or "RNBOsproInitialize Status - 12" when starting AlphaPro, it means that the driver for the USB Hardware Key (Sentinel Dongle) is missing.
The driver is included with the AlphaPro software installation, but has to be installed separately. See How to install driver for the USB Hardware Key
The driver can also be downloaded separately from the "AlphaPro" section at the download site.
