Quicktime/Flash CS4

I used MacDust (never again) to remove old unwanted files to clear up some hard drive space. When I opened Flash CS4 to work on a project-in-progress, the graphics were HORRIBLE! They were bitmappy and I thought I would have to recreate the animation all over. I reimported one of the images and it still looked all bitmappy, leading me to believe that the problem was a pref file in Flash. After researching, I trashed:

com.apple.iTunes.plist
com.apple.iTunes.Helper.plist
com.apple.iTuneshelper.plist
com.apple.iTunes.eq.plist
com.apple.quicktime.plugin.preferences.plist
QuickTime Preferences
QuickTime Favorites

This doesn't remedy the situation and I don't want to have to re-image my machine, Powerbook G4 667Mhz running OSX Leopard 10.1. (and yes, Leopard runs great on this machine, and my 400Mhz G4 tower)

Please. please, please help with a solution!

PS I also reinstalled Quicktime Prom but this was before trashing all the QT files. Hope this helps.
