One thing you forgot: After setting up the client, go to the Teams thread at the NPLB forum and post there that you'd like to register for Team Free-DC. AMDave or IronBits will get you set up in the DB as soon as they see your message.
Note: until you're registered in the DB as a member of Free-DC, your points will count towards team "-" (no team). Don't be alarmed by this; rest assured, this will be retroactively fixed when you're added to your correct team.
Note2: mersenneforum.org, where NPLB's forum resides, requires registration to post in most subforums (including NPLB's). When you post your first post, it won't show up immediately; again, don't be alarmed by this, because it will show up as soon as a moderator sees it and approves your registration. I'm pretty sure this is also how the Free-DC forum operates, but I figured I'd give you guys a heads-up just to be sure since we've had users get quite confused about this in the past.
