look for the mun background4allpages.cab at the bottom of the post, disable tf3d (start/settings/personal/today items tab uncheck tf3d) then install the .cab soft reset (stylus into little pinhole at the bottom), that should do it, then go to the settings tab in tf3d (right next to programs) and hit the wall paper option it will prompt if you would like to use the default wallpaper, select no and then select you own wallpaper.
