Edit, sorry misread your OP and that you are Lion to Snow Leopard, given that there was an issue with Lion I would suggest that there may be ab issue with the plug in again and contacting BG may be your best course of action.
Have you checked at the source, it appears there is an update that is meant to resolve the issues encountered by these plugins with Lion.

I should written Lion to Mountain Lion.. But anyway. I did't find any solution, so I gave up with this plugin and went to Davinci Resolve Lite way. Nice learning curve No more color tuning in FCP X. Recommend for everybody.
