Problem opening .mp3's

Hi everyone. New here.

I’ve had Audacity for many years. I use periodically but tonight I can’t open .mp3’s…

Would someone have a tip on what may be wrong?

Thank you.

It may be a problem with the mp3’s.

Is the problem with “all” mp3’s or “some” mp3’s?
Where are the mp3’s from? I’m guessing that they were not made with Audacity.

Try analyzing one of the problem mp3’s here, and let us know what this web page says about it (copy and paste the full information into your reply): MediaInfoOnline - MediaInfo in your browser
