Unable to load image

I am trying to load image to CC5000 10" with demos from NRF (mdz file is too large to attach here).

 

I have the mdz file installed on a USB drive and it is not finding it when I plug it into the device.  It just keeps changing from 'Unable to find MDZ file' and says 'Remove extra storage devices' and I can't do anything.  The same thing happens when I use an SD card.

 

Any idea how I can get the image loaded?
