I want to make my own voice for my TomTom One XL using my PC for free. I am using the website capitalnightlife.com.au/tomtom/ and have completed step 3 but can't get the win:viftool2 to work. I get the error message "Access violation at address 00477BC5 in module 'winviftool22setup.exe'. Read of address 00000000." Then it freezes and then it doesn't work from there onwards. Can any1 help?
