I tried to install this theme pack and the instructions from the theme pack said to rename uxtheme.dll in the system32 folder to uxtheme.old and place the new uxtheme.dll that came with the theme pack into system32 folder, that's what I did and the theme's are working except that my task bar is stuck in classic mode. I can change the frame around a window into something else but the task bar just stays in classic mode.
