You should press "Configure..." and fill out the details on the "Web" page.
You will need a Key to unlock your copy of visaj. If you installed from a CD, there may be a key on the CD cover. Alternatively you can connect to our web-site, give us a few details, and we will give you a key straightaway.
If you are not connected to the internet, you will still be able to evaluate Visaj, but you will have to run a local authentication manager program.
