Thanks for the reply, Well as you can see i really dont know what im talking about when it comes to file types etc.
All i can say is that i have a disk with a load of new plugins but only half of them work.
The files which work looks like a little lego brick (under info- its called a bundle- Universal)
The files which dont work look like a grey rectangle with the word EXEC in the top left corner, theses files wont open. Unix Executable File.
Sorry if this isnt very clear but its quite hard to describe my problem. Annoyingly my friends older computer, G4 tower with an older version of final cut, It works fine for him. I guessing its coz i have a new mac using the intel processor. Who knows. But thanks for replying anyway.
The plugin is called “Virtix”
