Been a really long time since I have been here and done anything. I have a new computer and have loaded the maps and mapsource on here but cannot get mapsource to accept maps, maybe I am missing the obvious. Thanks
How did you install the maps on your new computer? You can't just copy the files because Mapsource uses the Windows registry to access the maps. If you just copied them, you should delete them. Do you still have access to your old computer? if so, you can use GMTK to move the files: http://www.javawa.nl/gmtk_en.html
If you don't have the old computer, you will need to download the maps again from GPSFileDepot and run their installers.
