After turning off automatic renewal you will be able to use Expert PDF until your expiration date.
Head to the Manage Products section of your Expert PDF account. When the product says "Renews" it means automatic renewal is on.
- Click on Cancel Renewal next to a product.
- In the confirmation window click on Continue.
You will be able to confirm that the renewal is turned off as it will say "Expires" instead of "Renews".
