DigiTranslator 1.0.1 uses the DigiTranslator 2.0 authorization. You probably need to install DigiTranslator 1.0cs3 since you probably have a v1.0 authorization disk: You definitely don't want to use any of the v2.0 software pieces, since v1.0 is standalone and doesn't use Pro Tools at all. You would likely just screw up your Pro Tools install. v2.0 is integrated into Pro Tools 5.13 TDM and 5.3.1 LE and higher: It is also possible that the extensions you are missing are just the Pace floppy enabler and USB drivers for your authorization disk.
