I'm trying to sign into Games for Windows Live! using the XNA Framework v2.0. However, I just can't make it recognize my existing Windows Live! subscriptions -- neither one that's attached to my Xbox Live! Gold account, nor one that I created fresh on live.com. All I get back is "the username or password may be incorrect."

Reproducing this is very simple. Just build the attached project using XNA GS 2.0, and run it -- there's literally just two lines changed from the plain vanilla startup project. Try to enter your existing live.com e-mail address and password, and it won't work. Try to create a new profile, and press the "sign up" option -- it will open a web browser window that errors out.
