Nook HD+ problem solved

I have had trouble with my Nook HD+ trying to download files and pictures from my computer to my Nook. I have talked with Nook support and no help, had countless people checking out my computer. My computer would not get passed the "download" screen. It showed up on my computer as MTP driver not found could not update. But guess what!!!!! It was so simple, I searched the internet for solutions from uninstall all drivers, to it was the cable. Nope! On the Nook HD+ itself, go to your settings; storage management; Media devise was checked (MTP); I chose to check Camera (PTP). Guess what, it now shows up as a storage devise!!!!!! Now I have downloaded all of our unit studies so now we can school where ever we are!!!!! I am super excited!
