OK. I have now updated Mapsource to 6.15.11, patched it an put CN NA 2011 into the Folder ...garmin\maps\

With Jetmouse I have taken an Serialnumber. Now in MapSource the America Card ist listed as enabeld but if I switch in the view to it a Problem-Window get up. MapSource has a Problem (No maps found in Image) and after the "OK"-Button Mapsoure close!?
What could be wrong?
