Hi - a simple question this time

When I connect the reader for the first time I guess I'll be prompted to register it which I'll want to do to keep the firmware up to date. Can I do that without loading the Sony library software?
I'm hearing bad stuff about stability of that programme so I want to steer clear, not being able or wanting to buy from the Sony bookstore.
So can I register the device without having to load the software? and do you get prompted automatically to register?
Thanks - I'd like to know before I hit the wrong key and end up stuck because I'd be hopeless at getting out of a glitch.
Cheers
