After having a couple of my purchased dreams not working I contacted support at stardock and they gave me two different things to try.  1 - was to run a batch file that reset my dreams and deskscape, and 2 - was they had me re-install Impulse.  I believe it was when I re-installed Impulse that things seemed to start working... in the process I also downloaded Deskscape 3.1 and Voila it worked!  I am now able to have dynamic different dreams on my monitors.

I was having a lot of problems with my computer crashing after installing deskscape 3.1, (this was my 4'th install) out of the blue my system would re-boot itself, but it looks like the problem has been resolved by re-installing Impulse and re-setting my dreams.

Excellent news...
