Diane - something is wrong with your set-up...just not sure what it is. Mine, no matter what I do, works flawlessly. One thing you have to remember, as I said before, is
do not update the Libraries using the SDC Tool Settings...both WC Browser and SDC auto update the skins when you click on Skins and Libraries. Again, it takes a minute or so to do it (Broadband) and it doesn't appear to be doing anything (re:updating skins), but it is.
A couple of questions:
Do you use IE as your default web browser?
Do you have a Firewall, cookie killer or pop up stopper installed...if yes..who's?
You should only have two Stardock folders containing all your apps...are these the only two you have (any will be in the Program Files Folder)?:
#1 C:\Program Files\Stardock
#2 C:\Program Files\WinCustomize
Finally, is the SDC version installed: 1.30.264 built 46 and the WC Browser version: 1.29c(

.003 ?
Un-installing and re-installing, at this point, is a waste of time, so refrain from doing it until we figure out what's going on.
