failed to read from a file in C.

Hello, this error keeps appearing evevrytime I save my file to .MP3 or.WAV. I’m using AUDACITY 3.0 software. Kindly help me please…

Are you working with a saved project, or a new recording?
If it is a saved project, what is the exact file name, including the full path (for example: “C:\Users\Fred\Documents\My Projects\tiddlywinks.aup3”)
