Was working, now won’t play several movies.

It has been working fine and then suddenly several movies refuse to play. I’ll click on them but nothing happens.
Here are some log entries:

20:59:50.404 T:6892 ERROR: Error creating player for item D:\Movies\Passengers (2016)\Passengers (2016).mp4 (File doesn’t exist?)
20:59:50.404 T:6892 ERROR: PlayMedia could not play media: D:\Movies\Passengers (2016)\Passengers (2016).mp4
21:01:22.567 T:6892 ERROR: Error creating player for item D:\Movies\True Lies (1994)\True Lies (1994).mp4 (File doesn’t exist?)
21:01:22.567 T:6892 ERROR: PlayMedia could not play media: D:\Movies\True Lies (1994)\True Lies (1994).mp4

The file locations are correct. If I click on the file directly they play fine.
I tried deleting the database and rescanning. That had no effect.
I also tried removing and reinstalling Kodi. I have Kodi 17.1 on a Windows10 computer.

Thanks,
