The original iLok authorized versions of these plug-ins should still be located in: Macintosh HD > Obsoleted Digidesign Software folder > DAE Folder > Plugins folder.
Move these copies of the plug-ins back into the main plug-ins folder: Macintosh HD > System Folder > DAE Folder > Plug-Ins folder
Alternately, you can choose to reinstall these plug-ins from the HD|Pack Installer, but you must first remove the newer versions from the Plug-Ins folder, otherwise you will end up with duplicate versions of these plug-ins (and Pro Tools will still load the floppy authorized versions only).

Note that the initial posting of the Pro Tools 5.3.1 TDM updater for Mac installed DINR plug-ins that needed to be replaced using the process described above. The 6/19/2002 posting of the installer instals the iLok authorized version of DINR and does not cause the issue described above.
