Adding scenery to FS9

Adding VFR Photographic Scenery to FS9 has got me baffled. The usual procedure doesn't seem to work, when using Visual Flight Volume One (England and South-East England) with windows 7. It did work on my previous computer (same windows 7 and fs9), but not on the newly-purchased HP. The program downloads, the file appears in the Scenery folder, but won't add properly to scenery library. I followed the drill set out in the tutorial - except nothing happens when I click in the middle of the open window (as directed). Can anyone suggest where I may be going wrong - or offer a more detailed and illustrated- tutorial?
Many thanks,
