Actually the problem was a typo, you can download base 1.0.3.1 to fix it. If you have a lot of mods in shellstyle you can do one of the following:
1) Add the properties to
Shellstyle > Shellstyle:DocumentsLayout > atom(PreviewShineLayer) > TemplateBackgroundMake sure you do the same for Photos and Music (Generic and Games are fine)
2) In the shellstyle's UIFILE look for
- <if id="atom(RPaneCoverSheet_NoSel)"></if>
Under it you'll see the background code, if the says Shellstyle:PhotoLayout, Shellstyle:DocumentsLayout, or Shellstyle:MusicLayout then change the 43 to a 42.
