So to be clear: you moved the three Carenado folders from the “Official” folder to another drive and reinstalled the three planes via downloading them through the Content Manager and they still give you CTDs with an empty Community folder?

The only thing you can try is deleting them again and reinstalling them one after the other and look if the problem persists with all Carenado planes or just one. If the problem started with an update to the Piper, you should install that one last
