Tried to watch several shows vie Roku, message box says 'title temporarily unavailable. Try again later'... for 3 hours!

I am having the same problem I will be watching a movie and it will be on a while and then it will go back to resume and say title temporarily unavailable I will click resume sometimes it takes a minute to five minutes and it will go back to playing but it does this same thing several times through the course of the movie...UGH
