Not panicking but when your client tells you that you have no subscription and need to click here to activate, you have to wonder what's wrong don't you?
Either something is actually wrong and needs to be dealt with of bioware has done a lousy job of putting out information about what to expect. It's clear as mud when you read what's on your account site. It first says you need to enter and activate a code then has a code listed right below it. Real clear huh. NOT
It is confusing but you're fine. If you haven't got 'The Saga Begins' email from Bioware then you aren't in yet and your account isn't flagged for EA. In the email you'll be given everything you need to start playing.
