puffer1,
If you see the Download Station logo next to the textures you want in Content Manager, you have to download them by dragging them to the pane on the left side of the CM screen, then clicking Start. When they've downloaded, you'll see a laptop icon next to each texture.
If you see the laptop icon in CM, but don't see the texture in Syrveyor, you may not have committed them. Do that in CM by highlighting them and hitting Ctrl-M.
If you still can't see them in Surveyor, they may not be compatible with TS09.
I don't know if textures have dependencies as do the, say, locos, but if they do, some of them may be missing. You can check for missing dependencies in CM. Some of the assets I've tried to download were missing dependencies, and didn't show up in Suirveyor. I'm sure there are others who know more about finding them than I do.
