Doesn't Display On One of My Computers

The oddest thing is happening and I can’t figure out why. OA Social Login shows up fine on my Macbook Pro Retina 2013 but not on my iMac 2013. Both have the exact same software and setup too. Tried clearing cache, using different browsers, Chrome, Safari, Firefox, all with the very latest update and running Mac OSX 10.9.1. but it shows up on my Macbook and not my iMac. Just tried it on VMWare IE10

What could be the cause of this?
