Can anyone throw out ideas as to what happened? Here's what I did: iMac 10.8.? iTunes 11 Menu item "Add to Library". Selected 8 WAV files from a folder on my NAS. Clicked "Open" button. Nothing happened. Tried it again, but this time the folder the WAV files were in is now gone. What happened? Does Apple hate WAV files, try to convert them, and then failed, but instead of giving me my files back it destroyed them? Thats all I can think that happened. Makes no sense.
