Andy, glad to help.
Right the scenery thing. IGNORE the readme instructions is my advice. Everyone has their own pet place to put them.
Unzip the file into a temp. folder.
Now open the FS2002\ADDON SCENERY folder.
Make sure the file is something like Crete\TEXTURES and SCENERY. Drag it into the ADDON SCENERY folder.
Now start up FS2k2.
Go to settings, then scenery library. Now add scenery. It'll bring up a pane, on that click on the ADDON SCENERY folder, then on the folder Crete, and click OK. When you have finished adding the relevant files, then click on OK in the bottom right of the scenery library page, and off you fly.
