trouble using app

I have an Amazon Fire tv.  On Monday, we couldn't navigate around the Stream app and eventually would get an error and black screen.  I tried unplugging the tv and reinstalling the app.  Didn't help.  Since then, the app is behaving better but when we get to Stream, it only gives us a couple banners of tv shows we have already watched.  I navigate to the left side where Options are.  I can see To Go, Favorite channels, Search, Settings, etc.  But there is no longer a "highlighter".  So we don't know what option we are on and have to blindly select until we manage to get to a Guide to watch tv - or to do anything within the app.

Our other Fire tv is working fine with Stream.  Neither uses a stick.  They are the tv version.
