Found a cheap workaround:
Find the folder Community\aerosoft-vgds-driver\airports and select the airports you have bought via the marketplace as an example I do it for EDDK: aerosoft_eddk.xml. Open it up with any code editor and in the 3rd line you should find: packageName="aerosoft-airport-eddk-cologne-bonn". Copy that name and create a new folder in your Community folder with that package name. If the package name is separated via a comma e.g. packageName="aerosoft-airport-edlp-paderborn,aerosoft-paderborn" then only select one of the names not both.
After you've created the folder, create a new file in that folder with the name "manifest.json"
which contains the following:
{
"dependencies": [],
"content_type": "SCENERY",
"title": "",
"manufacturer": "",
"creator": "Aerosoft",
"package_version": "1.1",
"minimum_game_version": "",
"release_notes": {
"neutral": {
"LastUpdate": "",
"OlderHistory": ""
}
}
}
Make sure that the version from the xml matches with the package version in the json.
