Okay, so I finally got it to sign in.
Here's what I did: I merely connected my MBP directly to my modem with an ethernet cable. That's it. Signed in right away. I've tested it out back on my wifi network, and it works just fine.
Either my Netgear router, Vonage gateway, or 3G Microcell was interfering with the sign in process.
