Media player won't work for my roku 3 after the last update

I have the same problem with my Roku 3. The device does not show up in the Roku Media player and therefore cannot be accessed when any USB drive is plugged into the Roku.

This just happened a couple of days ago after an auto update to the firmware which seems to include the Roku Media Player, who’s icon was moved to the end of the app list. 

i have tried everything, updating, restarting, unplugging, using different devices, but no change.
