Serious question about registration code for online play...

I know half of you won't believe this, but I'll ask it anyway. So I bought NBA Live 2004, and played it on my laptop because my desktop didn't have a good computer card. I used the registration code on EA Sports Online to enable internet play, and played for awhile. However, I bought a new video card for my desktop and installed Live 2004 on it. So when I tried registering on my desktop for online play, the registration code I entered said it was already in use. Since it is my code in the first place, is there any way to let EA know that its me, and I want to use the registration code on my desktop?

Mmm, u shouldnt need to re-register, just use the same Username+pass to login that you used on your laptop. Have you used the same Serial code on you desktop as you did on your laptop when you installed the game?

Yeah, I logged in under the same username I used on my laptop, but it still asked me for a registration code, which I gave, but I got the already in use message.
