Some Icons gone??

[balcis]

i've installed some icon packages and something that called vista menu or something (i don't think problem's about that), and now my some "crux", "crystal-svg", "gnome", "highcontrastinvert", "mist", "pficons", "tango" and "tangerine" icons themes are gone!! i didn't deletede any stuff from those directories that /usr/share/icons or home/.icons.
here are two screenshots, any solutions-answers are welcome.
