Hatsan Hatsan blitz not firing just makes click sound each time I cock it an pull trigger

So I just took my blitz out right now an it shot a burst of 4 or so an it stopped an I though it jammed up at first but its just not firing now after I decocked the rifle last night, I cocked the bolt all the way back an let it go an press trigger just to hear a click as if I decocked the rifle again, Cant think of whats going wrong , I just pulled the bolt back 70% an hit the trigger to decock it last night now it wont fire.
