Are you turning it the right way, i.e. the opposite way to the other one?
Yeah I think I'm turning it the right way! Tried both ways as I got unsure of myself as it wasn't working. The first one, that worked, I turned anti-clockwise. The second one I was mostly also trying to turn anti-clockwise, but that meant the opposite direction to the other as it's on the other side of course. But yeah couldn't get it to budge in either direction.
