As part of our Summer cleaning, we have manually downgraded some members for whom we can't find any payment information. If you have been downgraded and feel it's a mistake, simply fill out a support ticket and show proof of payment which we can verify (e.g. a screenshot of the payment info, showing your user info, name, date, etc).
If you can still log in and access full member privileges, you are not affected.
I received one from PayPal but can still log in to access member content.
So far so good.
