Where is Breverb inserted? in the Pro Channel or in an Fx bin?
If it's in an Fx bin, is it on it's own Bus? If so, and this is probably the best way to setup a reverb suing the Fx bin, make sure that the send level is up on the track, the bus fader is at unity, the Breverb plugin is set so that the Dry level is killed completely and the wet level is at 0dB.
If it's in the Pro Channel, first make sure that the Pro Channel itself is switched on and also the Breverb Module
You will have to juggle the wet/dry sliders to get the effect you want. In this scenario the send level is totally irrelevant.
