Replay files won't play, no sound, nothing. Reinstalled per tech support, now files all missing.

Hi Dawn, 

Sorry to hear that you ran into this snag. Repairing any application included in Articulate 360, or the suite as a whole should not cause any of your files to get deleted. I went ahead and created support case number 03237911 for you so one of our support engineers can take a closer look at the issue. We'll be in touch shortly!
