Party Pack - How to Register on The Sims site? (no number ..

Archived from groups: alt.games.the-sims (More info?)

I just got the Party Pack (I'm quite late to all of this, I know!) and
would like to register on EA's Sims' site, but there is no number
printed on the CD case or anywhere else that I could find.

(I really did buy this, from J&R - it's not an 'evaluation copy,' lol)

Any clues as to go about registering my game there so I can have
access? Trying to find a way to actually email the site OR Electronic
Arts has been maddening.

Thanks for any help!
