Reply to Volume Problem with VCI 100 SE, Traktor Pro

I have a brand new VCI 100 SE 1.3 (got it 3 days ago). Using Traktor pro 1.2.1 and Audio 4 DJ.

When I'm mixing a set and load up a track, it plays fine. However, if I change the volume even slightly, barely moving the either the faders or gain knobs, the track's volume drops or increases dramatically and I have to move and adjust a lot to get back to where it was before I touched it. It only happens to freshly loaded tracks... once I adjust volume for that track, it won't happen again until the next track is loaded!

Also, in a set last evening , I forgot the Right fader down, brought in a song on the right deck and with the fader all the way down and the cross fader all the way over to the other deck, it played the song at full volume anyway! When I moved the fader up slightly, volume immediately went down to zero.

Because it's happening on all faders and gain knobs, do I have a software problem?
