Renaissance question / plugins won't load in MPC software

Hello

Under Mountain Lion: I installed properly all the MPC extensions (Bank, 809 etc).
None of them shows in my MPC software when trying to load a plugin on a plugin track, the popup window is empty although the VST files do show up in the Finder. Do you have any clue?

Please help thanks !!
