How to Tell if Pop-Up Pro Is Loading Files?

I've installed Pop-Up Pro, created an ad to appear for non-logged in users, but no pop-up appears when I use a browser that's not logged in. What files should I look for in the page source code to tell if the plugin even loads?

Also, I don't see a Behavior section that, among other options, lets me time the appearance of the pop-up. That's the reason I bought this plugin. Any ideas where that might be in the interface?

Thanks!
