problem with icons

hey everybody.
i have a big and strange problem. today i want to setup my miranda.
i applied an icon pack, but tthen i changed the contact list skin, so i thought this icons is not good for that skin, sii wanted to changing it again. BUT
the button, next to the 'load icon set' button, is gone.
i cant imagine what happened with it, but i cant change icon without it.
so maybe you people can say something smart.
i hope:)
please reply, thank you
