Here's the extracted bench:

They offered a code for the gnome.
I pre-ordered from there but have yet to receive my code.
So I don't know yet if it's the same one that we already have that worked for the planter and gnome.

You already have your game and pre-order code from them?
I'm still waiting on mine... 

Previous post updated to include base game paintings. 
On a related note, does anyone know which package file I can locate the Grilled Cheese painting in?
As I'd like to add that to my collection too but I'm having difficulty locating it.

I've put together a collection of the painting textures that come with Castaway Stories, quite simply so that I can handpick any that I would like to paint as a Custom Painting as opposed to having my Sim paint one at random.

Anyway here's the collection, if you think it'll be of use to you too:

Update: Now includes Base Game paintings, along with the two custom paintings that came with Castaway Stories.

To install them, simply place the image files into your Custom Painting directory.

Thanks Richief.
Just checked out the exercise machine in my game and it works perfectly now. 

When I place the exercise machine indoors, the object gets a flat black base on the floor.
However this only happens indoors and not outside.
Any ideas what might be causing this?

Here's the Castaway Stories terrains to complete your set:
http://www.megaupload.com/?d=D6KVHBH5

Inside the zip folder are two folders.
One contains the exclusive Castaway terrains that can't be found elsewhere.
The other contains old Sims 2 terrains that are present in Castaway Stories, albeit with different catalogue names and descriptions, I've included the Castaway Stories versions just for any completionists out there that would like to have the full tropical feel to the terrains they pick (Even if they're exactly the same as the Sims 2 versions.). They won't overwrite their Sims 2 counterparts though, so you'll end up with duplicate textures  in your game, just with different labels.

So if you just want the exclusive textures, you just need to add that folder.
If you want the re-labels too though, just add in the Re-Labels folder too. 

Yes they do.
Every single wallpaper/flooring contains their full name, description and pricing that Maxis assigned to them in Castaway Stories.
However I have corrected the odd spelling mistake that Maxis managed to leave in.

I've actually already done the Castaway Stories Wallpapers and Floors, including the ones that Xianah missed along with having repaired various spelling mistakes and other errors that Maxis managed to leave in.
So if you want them, you can get them from here:

I was planning to release them to everyone at the same time as the Castaway Terrains.
However quite honestly, I've just plain not bothered to do them yet. 
But since there's demand for the wallpapers and floorings, I thought I'd upload them early for you.
