WB not loading in Desktop Properties! :(

Running XP here. Haven't downloaded blinds in a month or so, but downloaded 5 or six in the past day or two. Normally, when download is finished, a text balloon appears saying "New windowblind skin installed" etc... Then I would go to Desktop Properties>Appearance and click on Windows and Buttons tab, and all windowblinds are shown there in the list. Now, none of the recent blinds I downloaded are showing up there. I have to manually open up WindowBlinds from the tab on the same properties screen, click on Install this skin now etc... and when I "X" out of that window I can click on desktop properties promts, "OK" "Cancel" or "Apply". When I click on "Apply" or "OK" in any order, the windowblind returns to the last used WB skin in the loaded "Windows and Tabs" list, which still will not show the 5 or 6 new WB skins I've downloaded. BUT... (drumroll please) when I click on "Cancel" on the Desktop Properties window, the skin which I've manually installed directly from the WB program, it will remain in place, THAT IS.... until I restart. Again, it returns to the last used WB skin in the Display Properties>Appearance "Windows and Buttons" dropdown bar list. I'm lost here. Anyone have a clue? Thanks.
