Pop Over not showing up in Brazil

I've set-up a pop up that's supposed to show in Brazil. My contacts say they do not see it. If I use a proxy server, I do not see it. I've installed your plug-in on the live site and the test site. If I set no conditions, the pop-up appears (live site and test site). If I set them as shown in the screen shot, the pop-up does not appear in Brazil. I have not yet checked to see if "anywhere but the USA" functions.

Please advise.
