Cake Poker Freeroll Registration Problem

[paul5562]

When I clicked on "Opt In" to sign up for the tournament and put in my screen name for a Cake Poker freeroll, I entered it wrong. I'm assuming that's why I'm getting an error when I sign up for the freeroll in Cake Poker.

Now, whenever I click on "Opt In" for a Cake Poker freeroll, my incorrect Screen name is already there.

How can I change it so it shows my correct Cake Poker screen name?

UPDATE: I think I figured out one problem. I hadn't created a "real money" account. Do I still need to change my screen name on this site for when I Opt In?

Thanks,
Paul
