MBC Mix and Match Bundles App

I am not getting a response to my inquiries. I have emailed back and forth with one person but nothing has been resolved. The app continues to state my bundle is out of stock when all my items are in stock. Also the widget disappears from the page when I click on a swatch. You state you have swatches for all basic colors yet black isn't one of them? This app is not working and I'd like to experience the timely response that others have posted. I have sales to promote and this is taking away from me doing so.
