Hi Binho. s2Member relies on notifications through the PayPal IPN service. This is how it knows when to demote Members to Free Subscribers; because Members are tied to existing PayPal Subscriptions.
If you need to demote Members on a schedule that you define manually, you'll have to write a PHP script that runs on a cron job. The script would need to go into your database, and look for Members without a PayPal Subscr. ID, and check their registration date, in order to make a decision.
In a future version of s2Member, we'll try to address this ( make it easier ). If you would like to see this feature added sooner rather than later, please consider making a donation. If we receive a donation towards this feature request, we'll see that it makes it into the next release of s2Member.
