I installed the AudioEase Speakerphone plugin to my PC, but it only appears in the FX selection of Vegas 8, but not Vegas 9. I've tried refreshing/rebuilding the plugin list and all, no avail.
I hadn't configured my VST plugin folders correctly in Vegas 9, and Speakerphone installed itself to a different folder than my other VST plugins, and Vegas 9 couldn't find it.
