I echo what Inayity just replied and also not completely sure if you are only having a problem registering your game on the legacy site. I am guessing that the message you are getting is because games can no longer be registered there, although I seem to recall a not-too-ancient thread here at social (I'll try finding it and amend this post if I do) stating that it actually IS possible to still register games there.
I believe all that the old game-registering procedure provided was a safeguard in case you forgot your CD keys, you could retrieve them from the site (of course that required you typed in the correct keys yourself since the procedure never actually validated what you typed in). Also, they may have been used to play some of the Premium modules although don't take that for gospel because I never bought those on-line through Bioware so am unsure how that whole deal worked.
Edit: Meh... it was a comment Urk made in
this thread a few months ago that must have stuck with me. It wasn't all that conclusive even then whether the old registration was discontinued or not. Not much help, but the question did arise back then about the time the forums closed.
