major addon scenery problem

so i downloaded some addon scenery for fsx.
i unzipped them, and it told me to put them into the addon scenery folder in fsx.
so imagine my suprise when i opened up fsx and there was no addon scenery folder!
it is nowhere!
i was looking everywhere for it, and its just not there.
then i realised that every time i start fsx up it says something along the lines of "cannot locate addonscenery-SCENERY.115"
what the hell is going on?
also i have a problem with my 747's wings. they are fine when taxying, but as soon as i take off, they kind of split in half, and all the moving parts of the wings (like flaps, speed brake etc) move up like they should. like when the wing produces lift the wings sort of bend upwards, but the rest of thw wing stays in a drooping down position.
wtf is going on?
