Alright good folks, Ol Nova5 figured it out again for himself after sending a email to Sd and continuing to poke around his system.
Here is how to retrieve the Desktop Earth and even the 3D Bouncing Box one that doesn't appear(even thou box is basic).
Don't worry about %username% not being your username, its a variable used by windows to make operations simpler for it, it will work to your advantage here.
just think of %username% being your username. for me its Nova5 so when you look at the real paths it would be "C:\users\nova5" for me, even thou i use the variable %username%
First.. open a folder window and Paste the following in the location / path bar.
C:\Users\%username%\AppData\Local\Temp\sdcentral\Mod_Dreams
See the files Desktop Earth.Dream_ and Bouncing Box Sample.Dream_?
(its best to open a second folder window here and continue on)
Copy both of those to a folder on C:\Users\%username%
I created a folder called Temp for simplicity in C:\Users\%username% create Temp there. Rightclick, New Folder, name it Temp. Copy those files there.
Rename boths files so they have no spaces in the names. i made Desktop Earth.dream_ into de.dream_ and Bouncing Box Sample.dream_ into bbs.dream_
then on the keyboard hit WinKey + R (this opens the Run Command dialog) enter CMD in the box and click OK.
a dosbox appears.. Now type CD Temp. You should now be in C:\Users\%username%\temp.
type Expand de.dream_ DesktopEarth.Dream (press enter)
type Expand bbs.dream_ BouncingBox.Dream (press enter)
Merry Early Christmas, you now have expanded both compressed .Dream files into a useable format, when you rightclick the desktop and pick Personalize, then Desktop Backgrounds. from the dropdown pick Deskscapes. copy both .Dream files into that location.
Its a little complicated for average users but if you follow it carefully or are a techie type it won't be a problem. You can't just rename it from .dream_ to .dream and get it to work, its in a compressed format that thankfully is the standard windows installer format which Expand can handle.
This ONLY works if you downloaded the stuff through SD Central.
