.wav or .mp3 files, even though I have burned these files before as audio songs on a CD. It is saying "the file has an unreconized file extension, it must be a .wav or .mp3" When I right-click the file, it says it is an "winamp media file." I have clicked on the View tab-->show files--->all files. W/o doing this, no files show up. I haven't had any problems before creating CDs, ever since I burned 3 mp3 CDs have I had this problem. All help would be greatly greatly appreciated.
