Ahhh...the saga continues....
Thanks for the kind words Andrea
Now, Tricia....avoiding for the moment that I think there's someother underlaying problem, let's just deal with getting you a skin! When you see the skin you wanted when you used the 'Install From Disk' option in WB config, you just need to click on that file and it will install. If, for whatever reason it doesn't, you can play with any of those options on the right without fear of messing anything up.
As far as version, open SDC and it will show which version you have installed and which are available. Installed should be: 4.19c(

.002 and available should be: 3.51.053. If that's not what you show that could be the problem. 3.51.053 is not an update so just ignore it.
The files that all these lovely things reside in should be: C:\Program Files\Stardock\Object Desktop\WindowBlinds. If that's not where yours are then that could be the problem.
Anyway, try installing a skin first and we'll work our way up from there. Don't worry, we'll get it
