This kind of issue is best handled via support. However, just a quick response.
It appears that we have not been notified by PayPal as we should of the payment (PayPal has a little complicated way of handling this), but we have indeed received the payment.
We have credited your account now, and also added an extra month for the inconvenience this problem has caused you.
I am very sorry, but hope that all is in order now. Please be aware that you’ll need to sign out and sign in again for the software to update it’s status.
