Non-functioning OM5569 NFC Explorer Board

I just purchased an OM5569/NT322ER NTAG I2C plus Explorer Kit and it doesn't seem to be working.  The identiv Cloud reader works fine and its light changes from green to amber when I put an NTAG device on it and Windows does indeed recognize both the reader and the NTAG device.  However, neither the Peek/Poke nor Windows Demo program recognize the tag or the Explorer Board itself, and the Explorer board does not power up.  The Explorer board's LCD display powers up but the Explorer board doesn't do anything if I connect it to a PC via the USB connector - though I understand from the user guide that the Explorer board is supposed to get its power via the energy harvesting function of the NFC tag.  The setup behaves the same way on two separate PCs running Windows 10.  Am I doing something incorrectly here, do I have a dead board, corrupt firmware, or something else?  Any help would be greatly appreciated.
