Hai,
You have said your FCP is newer version than your friend’s. Same thing happened to me when I upgraded my FCP 4.1 to FCP 5. Half of my plugins didn’t work. Later I found the recent versions of those plugins and installed them. But before you give up try this. Copy all the Unix executable files into “Macintosh HD/Library/Application Support/Final Cut pro System Support/Plugins”. If it works, it is fine. Otherwise forget it.
