Winterboard on 5.01?

How come none of the themes I had on my 4.3.3 work on 5.01? I have the same settings and all the files at the same place as before updating. However, the stock slider and the hideous slide show icon, are still present. Even with the themes activated in WB…

Also, is SmartScreen incompatible with IOS 5? I wanted the clock on the lock screen, and I had for a while, but it vanished and I can’t get it back..
