I’m brand new to Audacity or anything like it. I am suddenly unable to open any of my .aup3 files to continue working on projects, and I get the following error message:
So that puts the ball back in your court. Is this a problem with any and all Audacity projects or with a specific one ? What steps do you take to reproduce this error ?
Do you have plenty of disk space ? Can you start Audacity with an empty project and then record or generate some audio ?
Do you get this error after rebooting your machine ?
