I have Sonic RecordNow Audio, v. 2.0.0, in my Dell laptop I bought in 2005 or 2006. I have used it without problems until now. I have saved playlists under My Documents and I could always retrieve them. They now seem to be in M3U format, which RecordNow should be able to read. Yesterday I tried to get the file up and the message said "The file you selected could not be found on your system and has not been added." How did these files, always usable before, suddenly become unrecognized. And how can I get them to work again?
