I have tried several time uninstalling and re installing tomtom home on my Vista pc but each time I get the same error message, with the device not connected to my pc - "component returned failure code "Ox 80004005 (NS_ERROR_FAILURE) [nsIProperties.get]". Tomtom Home shows up as installed on my pc but it won't open properly. If I can't solve this it might as well go back to the shop!
