Attempting to connect BK-10 to windows pc.  I followed pairing instructions and it finds the keyboard but then gives message: "IClever IC-BK10 Keyboard driver error"

I have reset the keyboard according to other forum messages.

I have attempted after rebooting the pc.

I have tried each of the three bluetooth button options 1, 2, 0r 3

Same message each time.  

What other options do I have?
