Query: MasterCook 9 not compatible with Vista

I've used an older version of MasterCook for years and loved it. Recently, I purchased a new computer with the Vista operating platform. The older version of MasterCook would not work on it so I checked Amazon to see if there was a newer version available which would be compatible with Vista, and was thrilled to see that Amazon indicated that version 9 would work. I purchased it, installed it, and had a lot of problems. While attempting to learn why the new software wasn't working properly, I just learned that Amazon has listed the product information incorrectly. The software manufacturer, ValueSoft, indicated in their HELP guide that MasterCook 9 is not compatible with Vista...so BEWARE. I am very very disappointed both with ValueSoft for not keeping up with software advances and with Amazon for incorrectly listing the product.
