If you screwed it down tight then it can't pass any air into the plenum, it's basically a valve. Back it off (unscrew it) half a turn and your pressure should return. The further you open it the higher the regulated pressure on your gauge. Stop and about 120-130bar and see how it does. Anyway, I hope it this simple and nothing is damaged.
