It seems naming a scenery component in the add-on.xml is mandatory. You can fix it without reinstalling this way:
- Open the Documents\Prepar3d V5 Add-ons\Fsdreamteam KORD V2\add-on.xml file with Notepad or any other text editor
- Find this section:
<AddOn.Component>
<Category>Scenery</Category>
<Path>C:\Program Files (x86)\Addon Manager\FsDreamTeam\KORDV2\prepar3dv5\Scenery</Path>
</AddOn.Component>
And add a line with a name, like this:
<AddOn.Component>
<Name>FsDreamTeam Chicago O'Hare V2 - V5 Compatibility</Name>
<Category>Scenery</Category>
<Path>C:\Program Files (x86)\Addon Manager\FsDreamTeam\KORDV2\prepar3dv5\Scenery</Path>
</AddOn.Component>
Of course, this assumes you installed the scenery in the default C:\Program Files (x86)\Addon Manager folder. If yours is different, change it accordingly. If you have the scenery in V4 as well, do the same change to the Documents\Prepar3d V4 Add-ons\Fsdreamteam KORD V2\add-on.xml file, and make the same change, but use prepar3dv4\Scenery path instead.
Attached, a sample add-on.xml file for P3D V5 you can use as a template. Note the pathname of the V5-specific Effect is correct on the attached XML, this fixes the missing DL problem.
