WB5: No skins on list

Hello,
I'm experiencing a problem after purchasing and installing WindowBlinds 5. I've restarted my computer plenty of times and have skin folders within the appriopate directory which is my folder "C:\Program Files\Stardock\Windowblinds5". It appears that none of the skins I've downloaded form WinCustomize and the skins WB5 comes with are not showing up on my list of skins, only the two original skins my computer comes with by default (The XP and original default layouts) Oh, and I've tried browsing to the folders and no ".wba" or "zip" formats are within the skin folders, WinCostumize directly installs the skins to the folders, but nothing happens. I've even tried re-installing WB5 and I have the same problem. I look foward to any answers to my question. Anyone have a clue what I should do to fix my list so that all the skins I download show up on my list?
Thanks again!
