IR regulator - can't turn adjust knob

[PoorOwner]

I have a regulator made by I-R. looks pretty much like this

It says ARO on the knob on top, and direction to turn

3 years earlier I installed it, today I decided I want to increase the pressure a bit, I could not turn the knob at all.

any ideas? I even tried without pressure. I remember it was easy to turn and I think I didn't have to push down or pull up

Most regulators with Non-rising knobs (the knob doesn't screw in and out, it just turns, a splined shaft inside does move up and down, you just don't see it) pull out to unlock and push in to lock.

Regulators with a rising knob have a threaded shaft sticking out with either a knob or t handle on the shaft, it "rises" in and out of the regulator as it is screwed in and out.

Sounds like you need to play with it some more.

Some regulators you have to push in and then turn

I have the exact same regulator and I have to pull the knob up to turn it.
