OnDeviceError raised permanently

[dantch0]

Greetings,
The problem:
upon upgrading from Windows Integration CloverSDK release 1.0
to release 1.40
the DEVICEERROR event is raised permanently
Message: In ShowDisplay Order: The device is not connected

However Windows Device Manager shows
Clover Mini connected in Customer Mode!!!!

• Un-install & re-install USB Pay Display & Pay Display did not help
• removing CLOVERSDKK and USB drivers release 1.40 on POS & re-installing them back did not help
• Cold start of Clover did not help

The other Clover Mini units are still on release 1.0 & working
Please help
