all tracks now blank

Last night working on an audio clip in a project, I began to slip edit the left edge to show the hidden data ( an ess sound), and the larger image in the clip – a waveform that was a word -started moving in unison with my dragging the clip edge to the left, but it was moving out of where it belonged and was moving to the right. I tried a few times, and since I had a duplicate of this track, I got that section from the other track and tried to move on. When I hit play, I got a track not responding thing and nothing happening and everything faded. I waited and then saved the file when it came back to full visually, then closed it. When I opened it up, I got “a corrupt audio region was detected and padded with silence”. I’ve seen this a few times over the years and expected that funny clip area to be blank, but the whole project is blank. This is 24 active audio tracks, 6 archived audio tracks, and oddly 2 midi archived tracks. All blank. Haven’t done anything new since 5.10 update and worked lots since then with no issues.  I tried opening it in splat but got the same blankness. The audio folder has lots of audio files, but many are bits and pieces due to how I was working, and I’m not sure all are there. I have a saved file 2 hours earlier saved so it’s not totally lost, but never had anything like this happen before and wouldn’t want this to happen again. Thanks for any help, Treesha

Thanks for the reply. When i hit play nothing happens. No sounds or movement . I emptied the picture folder anyway, restarted the computer and still all blank with no sound. If i open one of the project audio folder wav files in sound forge it plays. No idea where the midi files went.

Thanks, i dont know where or how to check the windows log, can you point me to something on that? Looking closer lots of the audio isnt in the folder as far as i can tell, and the midi tracks data are definately not in there. This computer is only on the internet for the updates etc as needed and not online in many weeks now.
