Try going to site thru IE https://www.wincustomize.com/ and see if it does the same thing. If it works ok then it's something in your Skinbrowser. If it doesn't work jump on Stardock IRC and see if someone can help. It's probably something with your account......
I am using xp with wb 4.1 and oyther stuff should I save them in a different folder or what?
it has a location listed C:\PROGRA~1\STARDOCK\WINCUS~1\SKINBR~1\Download should I change that?
Check and see if that folder exists on your hard drive using Windows Explorer. If it does not then you need to either create it using Explorer or choose another file in your Wincustomize settings.
