I upgraded to latest version and can't get anything to transfer to PC now, it worked fine in earlier versions.
Just as a data-point: installed the latest version over one of the recent, earlier versions yesterday, and generally have had no issue in downloading from TiVo to PC yesterday/today, PS mode. The only glitch: one or two metadata files were not produced (I have the metadata file option switched on)--but this occasionally occurred with earlier versions as well.Exit out of the whole thing, and check the task manager to make sure all processes are gone.

Dan, did as you recommended and
