Another thing you can do, especially on fresh installs where you set a host name, is to use that host name instead of "localhost" or the IP address. Post installation, products will generally revert to localhost, which can result in a failure to load the management interface. Using the host name you set during installation should work just fine. 

Just a follow up, I installed this on a Dev server.  We have two physical servers for our Websites. Can I say fire-up a new machine on the network (Windows 10 as example), install the stats program and point it to the "shared" log folder on our network.

That way there is no new installation on our servers -- to avoid the potential of muckery!
