Anyway to reset audio?

I am working as a copyist for a client, and they sent me a file that for some reason will not play any audio other than the harp part. Does anyone know how to fix this? I tried resetting playback overrides with no luck. I also exported an xml and opened that. The audio worked on that one but the formatting is completely screwed up. Any ways to fix this would be greatly appreciated. Thank you.

In the Play menu, have you tried

Loading/reloading a playback template
Loading Sounds for Unassigned Instruments ?

That seems to have done the trick. Thanks.
