The sheepserver is delivering sheep again, so the screensaver should work again. Please donate to offset the expenses that I am now paying out of my pocket.
The authentication server isn't up yet so you'll still get an error "Can't connect to server, using free one" but you can ignore it and it should be fine. You can use the F2 key to check the downloading status. You will also get an error trying to enter your drupal login to the config page, just ignore the error until we get the rest of the server fixed, and don't enter your account info.
You can suppress the "Can't connect" error (and all errors) by editing your config file and setting "silent_mode" to true.
