COULD NOT GET 17.1

I successfully uninstalled 16.1 and then “successfully” downloaded 17.1 from Play Store. I got the KODI logo showing 17.1 and then waited until it opened for its first run. Then I got this weird screen showing:

‘Your library is currently empty. In order to populate it with your personal media enter FILES SECTION, add a media source and configure it. After the source has been added and indexed you will be able to browse your library.’

[and below were 2 clickable boxes as shown]

ENTER FILES SECTION REMOVE THIS MAIN MENU ITEM

I clicked on ENTER FILES SECTION and got nowhere with meaningless choices blocking me from entering the system. I struggled to no avail. Then out of left field I got banged down to 16.1. What the hell is going on here?
