Hiya... You need to delete large chunks from the pz3 and resave into your library as cr2 with a text editor such as Notepad. This is quite a process... I can't describe exactly which sections to remove at the moment... I'm at work. In the next update to PBooost, this will be one of the many new features.... ripping cr2s from pz3s. Won't be long!!!
