Hi. I think that the update for Win7 suffered with the WinCustomize upgrade problems. I talked to one of the WC tech guys and he confirmed that this should be fixed now. Could you try and download the version that's currently on there now? It should be the correct one.
If you still have problems with it I can check back with the WC support. It's should definitely be updated with Win7 substyle.
