Downloaded the free version to test on a number of PC's at home. One PC would not display the login page and had the error " the connection to the server has failed"
In my case it turned out to be ssl cache issue. In testing I could not get to ssl bank sites but could get to google and youtube via ssl.
Following the steps here resolved the issue.

Only created this post for info and future readers as I could not find specifics searching the forum with google.
Hope this helps someone.
