Vista - Vista button broken - remove "Start" text

Hi there,

My vista button is broken (see attachment).
When i first start windows it's okay, but after a press it ones it changes in a ugly button with the text "Start" in the middle.

I used uxtheme patch a long time ago so I tried to restore the backup files, hoping it would fix the problem, but then I can't use aero at all, so I applied the patch again.

Also it looks like the startbutton is hovering above the start-bar since i can select it and it causes a semi-transparant square above it. ??!!!

Has anyone got any ideas how i could fix this problem? Maybe by restoring the SP1 uxtheme files by using vista's restore system files? I don't know how to use it and I can't find the original SP1 dll's on the web.

edit: Maybe someone with Vista x64 SP1 can send me the original uxtheme.dll, themeui.dll and shsvcs.dll located in ..\windows\system32 ?

Tnx
