Ivory Vst Plugins

is pointing to the correct place where my 'Ivory Items' folder resides
I have tried to re-scan plugins but it doesn't do anything. All I can see for AU plugins is the Apple folder. As for VST plugins I don't see anything (I don't have any others installed, I just want to use Ivory).
If anyone knows what the problem could be please let me know, I've been wrestling with this for 2 days and I'm about to throw my macbook out the window.
