In the past, because ConCarolinas was a client event and not on our PayPal, we could not provide activation codes to our users. We have worked with CC Registration Department to get registration data from them enough to import them into our system. Although those activation can not be emailed out upon registration, they do exist and can be retrieved through OGRe. We update the database weekely so if you recently registered, chances are you won't be in the system until the following week.
Log into OGRe and use the activation screen to retrieve your code. It will be emailed to the email you provided ConCarolinas.
