a few days ago, i (accidentally) installed a demo of extra ichat & photobooth effects from apple.com. today, my bro and i tried to install "More iChat Effects", which is a free installation of non-demo ichat effects from apple.com. Because they didn't show up, we thought the demos were conflicting, so we uninstalled them. then i tried to re-install "More iChat Effects" and somehow it didn't work. the ".qtz" files were not showing up where they were supposed to, no matter how many times we tried. HELP PLEASE!
