Error on soundbooth CS5: crashes on start

I have Mac PC with OS X 10.6.4 and Adobe Soundbooth CS5. When starting Soundbooth and open Looks3_AE.plugin I got an error:

"Soundbooth has encountered an error.
[/Roadrunner/main/MediaCore/MediaLayer/VideoFilterHost/Make/Mac/../../Src/AEPluginVideoFilterModule.cpp-107]"
Or
Soundbooth has encountered an error.
[/Roadrunner/main/MediaCore/MediaLayer/AudioSupport/Make/Mac/…/…/Src/Mac/CoreAudioHost.cpp-551/
Looks3_AE.plugin is a plug-in for AE that has a Magic Bullet Looks. I tried to reset the settings for Soundbooth but this error keeps prompting. How can I get rid of this AE plug-in? Help please.
