This concerns a very old WavePad, v. 4.25 free version, which has worked brilliantly for the last seven or eight years. It does everything I want, or rather it DID everything I want until about five days ago. It now will not let me save any mp3 files. Every time I try to do this I get the message 'Unable to create file [file name] for saving'. It has never done this before. What has happened, and how do I fix it? Coincidentally, I only came across this problem after I'd installed ExpressZip.
All help gratefully received.
