I have Sony Sound Forge. I downloaded some songs into it (successfully) and they play wonderfully through my computer directly from Sound Forge. Then I saved the file, both as an MP3 and a WAV. Then I burned a disc and got a message that it burned with no errors. BUT, it won't play in my car, my wife's car or our home stereo system. I tried in MP3 and WAV. If I put the disc in my computer and use Windows Explorer to open the disc, it won't open. I know it's a simple matter - but I just can't figure it out. (I'm 81, but fairly good at this as I've burned discs before (with a different software) without problems. Any ideas? All suggestions will be greatly appreciated.
