My name is Mark Lundeen and I am new to animated wallpaper but I love it. I bought "Good Night Earth" from Stardock using the beta edition of Deskscape and it ran great for several days and now it just stopped and I just have a black background with the error message of the mpeg2 file codec. I read what the help said about Nero8 Ultimate making it function, but now it is only in a movie window and the laptopscreen is just black. I have cerebral palsy and it has taken me a long time just to type this post. Can anyone out there give me the steps to set it up to run properly again. I have Vista Business 32 bit edition. I really appreciate your help!
