MovieMaker Error messages while saving a project of ‘photos+songs”?

Few times it worked (in MovieMaker in Windows 10), but of late, not able to save photos with songs into a video and save it.  Saved file is used to burn DVD.  Saving suddenly stops showing Error message 'Ox887A0005' ' There are missing or Unusable files in your MovieMaker Project that are preventing your movie from being saved. Pl. check that file preparation is enabled in Options or remove the files and try again'. In Options it asks to Reset Settings of Chrome Browser, after doing this, another Error Ox87160138 appears 'movie can not be saved in selected Setting. Use another setting to save'. Despite changing settings, it can not save the movie! Please guide.
