I am in the same boat. Two services show up.
Select #1 and it says "This service account cannot be used in the current environment."
Select #2 and I get character creation screen without my existing character.
This is where I am at. I know my characters are on service account 1, they show up on here as linked to my account. I sent an email to SE about early access code being bound to the wrong service account, but who knows how long it will take to get a response. I got 3102'd pretty early last weekend, so I'm pissed off enough, and now I might miss out on early access as well.
