This is a common error for P3D (not for just the latest version but for previous versions too).  I would simply move your dll.xml to a temp folder or rename it (there might be two, one in the folder where your p3d.cfg is located and one in the new location where the scenery.cfg is located).  In P3D, the dll.xml in the location where the scenery.cfg will be rebuilt with the entries placed there by Lockheed Martin during the default installation.  If it fixed the problem, then you had a corrupted entry in your dll.xml caused by a subsequent addon and the entry could not be added to the addon menu properly.  I fear this issue is a result of using the Estonia Migration Tool to install an old product not made for P3D (see page 14, AVSIM CTD Guide).  I and many others do not use the EMT and thus have never seen this error.

 

Some others have reported they fixed this problem by reinstalling the latest version of the video card drivers.  If they are already installed, reinstall them with Admin Rights.

 

Best regards,
