Yes. Stuff you have bought from Microsoft is also getting updated from Microsoft.
Stuff you have bought from the Aerosoft shop or any other online shop like e.g. SimMarket (meaning: not the in-game marketplace) is getting updated via AS Updater.
Updates will be made available to Microsoft the moment they are getting released also in the AS Updater. It is up to Microsoft to make them available in the Content Manager, and totally out of the hands of Aerosoft.
Came searching for information on the forum, as I am also experiencing the issue reported in the first post. CTD when I request pushback at ENVA, tried at a few different gates. Bought ENVA from MS Marketplace.
If this is what I think it is try the following fix:
Rename the file "Aerosoft - EHAM Airport Amsterdam/custom objects/EHAM/lchtstrknd.obj"
Copy the attached file into the folder "Aerosoft - EHAM Airport Amsterdam/custom objects/EHAM/"
Hopefully the scenery loads fine after that, the downside is one of the street lights will be missing until there is an official patch available.
