Mp4 won't play after upgrading to latest version.

Using Windows 10, Mp4's will play in preview but not in live window. True of videos created using Wirecast and elsewhere. Tried a separate user interface created with Wirecast many months ago and it plays fine but not in our more current interface. Looking for a setting.
