Mishky, in my experience the hopper turns. *Perhaps yours is simply a little loose and needs to be pressed down into place (gently).
If you were running the grinder with coffee, while making those 10 turns, you would have gone through quite a lot of coffee. *
If you adjusted the grinder while it was stationary, then it is very likely to have jammed coffee between the burrs - a bad and very annoying thing to happen, as the usual remedy is to dismantle the burrs so that they can be cleaned.
PS: Sometimes, or perhaps I should say, a lot of times, there is no need to make anything more than a tiny adjustment with any grinder. Up or down dosing can produce nicer results than adjusting grind settings. ;)
