Audio file won't open

I was using Audacity last night and all of sudden when I was trying to open up my audio file back up again, Audacity gave me an error. I ended up sending the audio file to a friend who also has Audacity and it also gave her and error. The error message is attached to this message.

For what and how long was the show? Audacity 3.1.3?


Yes, so as you have already figured out, this is not a hardware problem - it is an indication that your project has been damaged. The good news is that in many cases, you can fix it yourself. Please read this forum post: Corrupt or Otherwise Broken Audacity Project Recovery for instructions.
