hi, i had installed the Navigator free sw on my xp tablet and it worked so far. But then i started installing maps. For the first run i have chosen to much maps, so it took to long to download all the Maps, so that i have canceld the Download. Then i tryed to install maps again, but the Botton is not working anymore. So i tougth it is best to remove the complete sw and start from beginning. But now the setup programm will not let me install anything but the install program. What can i do?
