Any dopers use StatCounter on their pages and have this problem?

I use StatCounter (statcounter.com) on my site to track hits. The counter on the main page is supposed to only display unique hits. I have the counter code on every single html page on my site to track visitor paths. All is installed just the way they tell me to, and it all worked fine until the other day. then it started displaying pageloads. the setting in my prefs on the statcounter site is still correct, and i havent changed the code. has anyone else noticed this problem with their site using statcounter?
