Welcome to the DVDFab forum here at CD Freaks
Is there some reason you have not updated the program for so long ? the latest version is 18.104.22.168 beta
It is kinda hard giving help when the program is that far outdated, many things have changed since that version
It sounds like the problem may be with your drive/burner, are you selecting the drive/burner in the target window ?
it will help if we knew some info on your system…also how much free space you have
