Popup keeps popping, does not expire or stops coming back

Hi ,

I installed popup pro and my LIFETIME popup keeps popping! Even if I select Close button acts as “Never see this message again” link the pop up keeps popping.

I am thinking its because of the hummingbird caching features so I deactivated them. Still pops all the time. I clear my browser cache…still pops all the time…I deactivated the pop up plugin..still pops all the time…I deleted the pop-up plugin…still pops all the time….

I really need your help..its driving my customers insane and affecting sales.
