Same problem here too. At first I thought it was a software/ access-ctrl/ elevated privilege confliction problem because I ran freescan from a limited account. I also ran it from an Admin accnt and as well as through an elevated console; same problem with it shutting down when played through freescan-- on XP through Win7. Different versions of net-frame, same results.
However, my scanner(BCT-15x) is sending the recorded signal through the card and it is being saved in mp3 format to said directory, but none of my mp3 players will play it with audio and I am lost. I probably should start a new thread though.
