I did a scenario and instantly i got pzb braking active.. but how do i get the train back moving when this happens?
First, after complete stop, set the throttle brake lever to exact zero. Then press PZB free (the middle PZB knob). The brake system now should reload the brale pipe. Just wait half a minute or so. Then you should clear to go further.
I haven't yet experimented with PZB, since it's not required in any of the scenarios or sessions I've run (but I haven't tried many of them yet). Did PZB just turn on all by itself or did you activate it -- perhaps by mistake?
