I bought  the NYC airports x packages and have kewr an kjfk and the regional airports installed correctly. However, I had imaginesim lga installed prior to. I tried uninstalling klga from imaginesim but it is still there. The NYC x lga doesn't seem to take priority and the imaginesim scenery seems to stick there. Any tips on getting rid of that so NYC x can take over?

My first step would be: Look into the scenery library and deacivate what's left of the old stuff and move the other NYCX-stuff to the top.

I should have mentioned that there are airports in my library (mostly payware addons) that are greyed out and I cannot click on them to either remove or move up or down priority wise.  I'm not sure why that is. 

These are the addons added by the new XML method. There is a thread here about this, I am not an expert here :-)

What is the new XML method?  For a majority of these sceneries, all I did was run the V4 installer and it was installed.  I didn't do anything special with them.  A few airports I installed by changing the directory to V4 instead of V3 and manually installed but not LGA. 

take a look here:

Basically the addon are listed in an XML file called "add-ons.xml". this is the new method. Everyrhing installed this way is greyed out in the scenery library.
