Hi guys, After a bit of help here. I am new to GPS but not new to technology As I am off to Laos tomorrow with Happy Feet & Marcus, I have downloaded the Rotweiler maps for all of Thai and Laos and am trying to unlock them using Mapsource (version 6.13.7) and when I select "utilities/unlock maps" I get a message from Mapsource saying "Unable to start UnlockWizard. Please reinstall this program and try again" Well, I've done that and run a registry cleaner between installs but to no effect. Anyone have any ideas? BTW, I don't think this influences things but I've registered both my unit and my Mapsource disc. With thanks in advance, Pikey.
