Channels disappers

I use ProgDVB Pro 6.48.03, and nearly all channels i press, disapper from the channel list at left after I have seen it or recorded it. It's a very bad bug !!! The Arqiva feed on Atlantic Bird 1, 12,5W , 11161H 5632 (3/4) with NBC shows early morning (Cet ) was in the channels list yesterday, I programmed a recording from Cet 05:00 to 09:00 and after this the channel was missing. I can scan in this channel on daytime, 'cause this transponder is not on . They start it right before showtime . I cant stay up hole night to re-scan this !

Please help ?!!
