I just recently (today) downloaded the optional update for Dream Scenes #3.
Now none of my scenes will run, even the ones that worked before I did this
download. I have tried restarting the computer, uninstalling the update and
re-installing the update. I get the error message that there is an error
decoding my file. I have searched the internet, and can't seem to find much
of anything on this subject. The dream files do work when I play them in
windows media player, but will not work with dream as a background, even
though I got them via this and previous updates. I am running Vista
Ultimate, which was the original operating system on my computer when I
bought it last July (2007). Any assistance would be appreciated.
