Hi. I just downloaded the software from the TomTom site and installed. When I try to run it, I get an error. I've uninstalled and reinstalled several times. Customer service says I must use an older version, which makes no sense to me. He asked which OS I use and I said Windows. Based on that alone, he said I should use older SW. Why do they offer the SW for Mac or PC if the Windows version doesn't work?
