NU 15.0 Doesn't Recognize Google Chrome

I have 3 browsers installed: IE9, Firefox 8, and Google Chrome. NU 15.0 recognizes both IE9 and Firefox 8.0 but not Google Chrome (16.0.912.63). I tried uninstalling Google Chrome and reinstalling but NU 15 still doesn't recognize it. I'm running Windows 7 Professional 32-bit.  NU 15.0 is up-to-date as well. Any ideas?

 

Thanks,
