    C-Map 4D moving to new laptop

    I upgraded to a new laptop because of Windows 11 and transferred everything successfully except for my C-Map 4D maps.
    I had to move the C-Maps via USB drive because they are not available for download anymore On The Cloud. The maps registered in MyMaps and show as Ready in On The Device in MyMaps of my new laptop.
    But Expedition doesn't seem to register them and they don't show in the C-Map pop up in Expedition nor can I select them as map.

    Does anyone know what might be wrong? Or what the right process is to transfer C-Maps 4D from one laptop to another so that Expedition recognizes them?

    I use Expedition 4D 12.7.11 and MapsManager 2.30.2.0.

    Many thanks for your help.

    Maybe it is possible somehow, but I don't know.

    The chart registration and install needs to be done with Maps Manager. 

    Of course, if the charts you have are no longer available to download, that suggests they may be obsolete and either updating or moving to (eg) X-Charts might be worth considering.

    You're probably right that upgrading the map is the way to go.  My last update is just over a year ago and I was hoping to avoid doing it until next season. 
    Anyway, unless someone in the community had the same issue and found a way to manually transfer the maps that's what I will do.
