Garageband 10.0.0.2, plugins not working anymore

Mow.gli,

GarageBand 10.0 can only use 64bit VST plug-ins, that conform to the "sandboxing" requirements. Check at the manufacturer's site, if you have the newest versions of your plug-ins, or if there are updates available. If yes, update. (GarageBand for Mac (v10.0): Unexpected behavior with Audio Units plug-ins)

If your plug-ins are compatible, but still not working, reset the Audio Unit Cache and force Garageband to rescan the plugin.

1. Disable Audio Units in Garageband preferences
   - a warning is displayed, click "Continue"
2. Quit Garageband
3. Delete the following files from your User Library, if they are present:
   ~/Library/Caches/com.apple.audiounits.cache ~/Library/Caches/AudioUnitCache/com.apple.audiounits.cache ~/Library/Caches/AudioUnitCache/com.apple.audiounits.sandboxed.cache
   
4. Open Garageband
5. Enable Audio Units in preferences

Note: Your user library may be hidden by default.

To reveal it, use the "Go" menu in the Finder's menu bar. Hold down the ⌥ key, while selecting "Go", then the User Library will appear in the menu. Open the Library and look in "~/Library/Caches/com.apple.audiounits.cache" and the other caches I mentioned. If they exist, delete them.

I've tried everything I could find online (including the procedures on this thread) on how to resolve the issue of installing Garageband 10.0.2 and carelessly hitting the "ignore plug-in" upon initializing GB for the very first time.

The only thing that has worked for me to have my Waves plug-ins work is creating a new user account. When I did that and fired up Garageband it instantly scanned my plug-ins and worked. So...I know it works on this computer and all the plug-ins are compatible but why can't it work under my admin account?
