Aperture 2.1.4 crashes shortly. Recently upgraded to SL.

Question

Hi. I'm sorry if this issue has been resolved in another post, I've been looking around but I haven't found a resolution.
After upgrading to Snow Leopard, Aperture will begin to crash while I am browsing in a project. I was surprised to find that others have posted about Aperture crashing so I hope there is a solution. In another post, I read about duplicate fonts being an issue and have already removed dupes but I still crash. If anyone can help I'd greatly appreciate it, I have a deadline coming up =).
Below is the crash report:

I case you did not see my update this is the error
Dyld Error Message:
Library not loaded: /Library/Frameworks/PluginManager.framework/Versions/B/PluginManager
Referenced from: /Applications/Aperture.app/Contents/MacOS/Aperture
Reason: image not found
I checked and all the files seem to be in place and are current 2.1.4
