Ok.
I've download basemap and copied to iGo\content\map
I've delete folder save
i've renamed license folder in licence (i'm stupid...).
But now at least i've an error message: It's non possible to open filemap with the license provided).

I've downloaded maps from:
[Only registered and activated users can see links. ] post n#3.
Maybe i need another licence for truck ftr? I've no buildings.

Thank'you for your help!
