Hi Michelle, it's a weird issue that it might be a bug on the new version (3.1 SR4). Try to refresh your browser and eventually it will work (don't know the reason yet, but as I told you I've started experiencing the issue with the update to the 3.1 version).
Thank you for your help! In the end it was a combination of things. We are still not sure exactly what was wrong, but the biggest of the issues was my virus protection. I had to completely uninstall before Qlik would work. We also had to play around with compatibility on Qlik as well as a weblclient service. But finally got it running!
