Yep, that fixed it! Thanks

I also needed to use wav files (mp3's won't work, at least not on my system).
I threw a couple of the toughest conversions that I know of at it to see. On the whole, the primary AI over in the other topic is superior, at least presently, in that this one has more trace vocal across the tracks, like a lingering echo instead of the static the other one gives ... but both are in the same ballpark, which is way ahead of any other program.
One fascinating thing though, is that this one actually seems to handle some things BETTER than the other.. though I'd need to do more testing to see. I'd say this is the exception, not the rule ... but... For example,
Steven Wilson - Blackest Eyes it does a poorer job of the verse sections, but does a superior job on the bridge. On
Smashing Pumpkins - JellyBelly it does a poorer job on the overall vocals, since there is trace bleed here, and the other AI eliminates it entirely, ... but on certain parts of the song, the other AI completely fails to remove any vocals at all, and this one does not do a perfect job by any stretch, but it does a noteworthy better job on those parts.
I've had very little time to test, and I know that there are more builds to come (which I look forward to), just very early observations. Genre specific models fascinate me as well ... what if that one part in a Rock song converts better with a Pop oriented model and can be sliced in with the rest of the song converted with the Rock model to create a complete product? I'm already getting that vibe just comparing this model with the other one. Even failing that, more diverse coverage of quality results is likely.
