Using DP 4.12 I had successfully imported a series of CD tracks into my project and tracks. And then for some reason it stopped working. The new ones I import ONLY play from the Soundbites window, not from the tracks that I dragged them into. I've compared them (44.1kh/16bit, aiff L/R etc.) in the info window and they are the same. The older ones still work correctly. Why is this happening? What could have changed? It's not the CD's themselves. Previous "good" CD's don't work now. I would appreciate any help here.
