We experienced synchronisation issues with NetBilling and epoch our two primary paiement processors over premium membership rebills. The short version is they did not tell us when a rebill was processed for a customer, they were waiting for us to ask. We fixed the issue with NetBilling already and are working on epoch now. We'll make everything straight before the end of week. Please be patient if you have been rebilled but lost your premium status or in any abnormal other scenario, there is no action needed from your part and it will be fixed hopefully tomorrow.
Sorry about this problems, we appreciate your support.
