you probably have an error in your dx current theme folder.C:\Documents and Settings\Owner\Local Settings\Application Data\Stardock\DesktopX\CurrentTheme. 
  If you delete all content and reload a theme should be fine.  
  Also, If this fails to help,go online open the stardock downloads page see if it 
 loads correctly.If the icons won't load open c/programs/stardock/stardockcentral/
downloads then put all downloads in a new folder.they won't show anymore but if
you have a lot like I did they can cause problems.
  you can still veiw and work with them by going directly into the new folder. I had 
other issue's with DX running and this fixed them.  
  good luck
