When Rambox tries to charge your subscription and, for any reason, the transaction is rejected, a notification will be displayed saying that we were unable to renew your license. 

In this case, we'll try your payment again over the next few days. To keep your Pro features, you may need to update your payment details.

If your payments continue failing and you do not update your payment details within the next 7 days , a new notification will be displayed inviting you to re-subscribe to a plan o buy the Lifetime license by going to the Billing Section; otherwise, you may switch to the Basic Plan.

After your resubscription, you shouldn't see this notification. But sometimes our payment and license services take some time to syncronize, and this could cause unexpected "License expired" notifications, so please wait few hours. If you keep seen this notification, your license expired even you resubscribed, or you have any trouble with your license, please contact us through a support ticket. 

Keep in mind that if you purchase a Lifetime subscription, your license should NEVER get expired. As said, if you still have some trouble please contact customer support.
