You culd also open your PT, which is working - and *without loading a song at all so that settings won't be possibly changed* - go to Prefs -> Audio and grab screenshots or jot down all the settings as you find them there.

Then open RB and compare those settings in order to find out what might be different there.

If you find somethings set differently, change it to the way it is in your working PT copy.
