Pop up pro deactivated but pop ups are still popping up


I've had Pop up Pro working for a while and I've just installed Hustle too to see what it's all about and I see that it works with Popup Pro somehow.

Problem is that I am running a promotion and I don't want any pop up's at all for the time being.

I deactivated the pop-ups in Pop up Pro but they still come up. So I have now deactivated both plugins and the pop ups are still there for site visitors.

Can anyone tell me what setting have I missed to turn them off or if there' another plugin creating them somehow?

I'll allow access in case someone needs to take a look.
