Problems with new Zip Tools software included with ZipPlus

Louis Wheatcraft purchased a new ZipPlus drive. It came with Zip Tools 6.0 (a version not yet available on Iomega's web site as far as I can tell). Louis writes: "The main software for basic drive operations (Zip Tools 6.0, Copy Machine 1.2.3, and the Iomega Drive Options 1.3.1 control panel) will not work on my Performa 6320CD. They try to launch but then just freeze." He claims that Iomega Tech Support told him that they are aware of the problem but didn't have a solution. In the mean time they said to go to their software site at and download the file "Macintosh Driver Version 5.0.3."
