been using the eclipse for a couple years. plugin has always worked great - 10.5. & 10.6
i'm currently on the latest version of everything with no trouble.
i will say i was NEVER able to get the ethernet software to work until very recently when their tech support realized there was some weird MIDI file buried deep in my system after they had me send them some kind of report from terminal.
have you called them?
