Uninstalling Plug-ins, Cleaning up TIGER Options

[beauty_speed]

hello all

In order to uninstall plug-ins (AU, MAS or VST), do I need do more than remove the .component icons in the correspondent folders or are there any other files that keep the plug-in´s active in any way ?

Final Cut Express does not open and I suspect it might have something to do with Waves plug-ins. However after removing older versions and installing new ones (which they claim no longer produce crashes), the same thing happens.

How can I clean up my entire plug-ins from OS X ?

Thank you.
