It looks like you are talking about the account "mrkeath", although that has a different email then your forum account. If so, your account was created on our system fresh, and then you bought a subscription for a month on the 12 of January. It isn't linked to an old MF account in any way. What should have happened is that you used a link sent to you to create the account. That would have linked it.
I did find a code from MF associated with your current email that provides Seaside though (username ZZBrent). Let's hope that name is familiar to you and just assume that it's you. I added Seaside to your account.
