I downloaded Audacity because I'm doing part of the chorus Be Prepared now. It was working normally, just an annoying sound but it's probably my microphone. So I decided to sing some musics I like to test it. I sang Simple and Clean and exported it to my computer, in WAV format. The result was good and works in my computer. Then I sang the Be Prepared, save in WAV format and it worked too. But now I sang another music and when I try to export it to my computer it says: The / is ON the letter O. I don't know what this thing means. Then when I see the folder I saved the file, it is there. Normal. WAV and everything, but when I try to open it on my Windows Media Player it says something like this: And doesn't open it. Does anyone know what happened? And how can I fix it? Thank you in advance. EDIT: Another recording program may be useful as well.
