Stardock Central skin and theme browser does not display thumbnails

The Stardock Central Skins and Themes browser doesn't display thumbnails images in the Wallpaper library. I can get no browser view of the thumbnails. I can, at least, get the large preview to work, which keeps me from downloading a bunch of stuff I end up not wanting, but it's more than a little annoying. The only way I can get the thumbnail to display is to actually download the file. Then I see that thumbnail, but still not all of them. This problem used to occur only in the WindowBlinds category, but in an attempt to fix it, I uninstalled WB 6, reinstalled WB 5, and then uninstalled 5 to reinstall 6. Now, as I said, the problem has switched to the Wallpaper library.

System: I am an Object Desktop subscriber and everything is up to date as of this morning. Windows XP Pro SP-2 and up to date on that, too. I can't attach a screen shot of the situation here - I don't have anywhere to upload it to so that I can supply an URL.
