Conservatrice review for Retail Barcode Labels

This app doesn't work. I use to be able to print beautifully designed barcode tags. I can't even get my Dymo to at the least get the correct sizing to print a generic looking barcode. You guys need to fix this quick, or bring back the old app that actually works. It's not even a fact of user friendly, it literally does not work with my Mac and Dymo.
