GarageBand keeps a cached instrument list file which it modifies from session to session. When GarageBand loads an AU for the first time and the plug-in causes Garage Band to crash, the AU is marked as invalid and it will not show up in GarageBand again.

To fix this problem, you must delete the following file from your hard drive:

/Users/<yourUserName>/Library/Caches/GarageBand/com.apple.GarageBand AU.plist

Note: In this path above, replace <yourUserName> with your account name.

After deleting this file, relaunch GarageBand and Dimension Pro will show up fine.
