If your Puzzle Society account currently has an expired status, then that is why you're not able to play games as usual at www.puzzlesociety.com.
An attempt to automatically renew the membership was made, but the credit card transaction was declined. An email was sent to notify you, and we're sorry if this message did not reach you.
To provide new payment information and renew the account, please go to www.puzzlesociety.com and log in with your username and password. Click on any game and hit the green "Start Free Trial" button. You will be prompted to enter your new billing information. This will renew your membership and give you full access to Puzzle Society games once again.
