losing files with doubletwist and airsync

[bigmac1197]

I ripped a few cd's I had on hand.They seemed to go good using dt with airsync.I saw them on the phone(Captivate) and could play them using music player.Tried them the next day and they are gone!!I can't figure out where they went!Are there instructions about dt and airsync?I tried under the help pulldown but it doesn't work either.I'm going nuts!!Any help out there?
