The 503 Service Unavailable error is an HTTP status code that means the web site's server is simply not available right now. Most of the time, it occurs because the server is too busy or because there's maintenance being performed on it.

Try again and see what happens.

Thank you for your reply.

I have been trying for hours now actually, but the same result

Now i uninstalled 3.5 version and reinstalled older one, seems to work for most of the books now, with one or two exceptions.
