Hi, I noticed yesterday that one of my songs wouldn't play, it would just skip to the next one.I checked my iPod which hasen't been synced since the day I started importing them a few days a go and it plays, checked Traktor and it had ben analyzed and is now in the Traktor library so the files must of been ok to start off with. Now it won't open in Traktor either. I was playing through some tracks today and 1 made a glitchy sound & just cut off & started playing the next track. I did the same thing to check this track on my iPhone & Traktor, then because I could open in it in Traktor I could see it had analyzed it & that the waveform was there & it was there to the end of the track but at the part it cuts out the live (large) waveform goes blank. I'm very frustrated, i've been using my desktop PC to prepare my tracks, 1st i've used Platinum Notes converting to wav so i've had to re-tag but I thought it would be worth it and i'll only have to do it once! Then i've been converting to apple lossless, tag keys with KeyFinder then transfer over to my laptop,then analyze in Traktor. A long process but as I said I thought i'd only be doing it once. Please help! EDIT: I have transfered the corupt files to my desktop PC & i'm getting the same problems in iTunes & Foobar2000. I'm not sure if it's iTunes or the HDD.
