If that was your only copy, your misfortune. Condolences. But that won't get your data back and I have no answer, but for the ounce of prevention.
Regardless of how good or bad InCD is, I trust nothing. Everything I have of value, like family photos and good music (C&W, of course), is backed up on a second hard drive and CD-Rs for double redundancy. I only use InCD as a temporary collection point prior to burning out to CD-Rs.
