Hi, I first listened to the program probably 1.5-2 years ago. It helped me alot, but my symptoms came back, so a few weeks ago I picked up the cds to listen to them again. The problem is that CD # 2 now skips. I can't listen to lesson 3 at all, because it completely skips through it. There is also some skipping in lesson 2. Why would this happen? Or is it a problem with my CD player?
