Discjuggler 3.0 Problems...

I have a full copy of Discjuggler 3.0 and as far as I know it works with my burner, but when I attempt to burn something data never gets written to the cd. I just started burning backups and have gotten around this by using Nero and other things but using Discjuggler would make my life so much easier. Can anyone help me fix this. Everything seems to be working perfect but the laser isn't writing anything to the disc. The light on my burner that indicates that the laser is in use even comes on. Can anyone help me?
