Commented Unassigned: Cannot locate resource 'themes/aero/images/htabgroup.png' [19842]

Hi
I upgraded my project to WPF Toolkit 2.0 but when try to run application, get this error

__Could not load file or assembly 'Xceed.Wpf.AvalonDock.Aero, Version=2.0.0.0 .....__

by using reflector and go deeper it brings to

__Cannot locate resource 'themes/aero/images/htabgroup.png'__
and
__Cannot locate resource 'themes/aero/images/vtabgroup.png'.__

please fix it (waiting for new build)

thanks
