I upgraded my HOME from 2.1 to 2.2 (automatically) for my Go 300. Now I cannot open HOME on my computer. I uninstalled and reinstalled and still no luck. Got an email in to TomTom support. Hopefully they will have an answer. But I would like to go back to 2.1 and I don't have the file. Does anyone have the 2.1 update I can get?
