If you use a regular credit card to pay for Screenshot Monitor services - it is charged automatically every month for the previous period. However we can not automatically deduct money from your PayPal account because the amount you are being charged can change from month to month and PayPal does not allow such charge.
You options for automating the payments are:

  1. Switch from PayPal to Credit Card
  2. Add money to your account (find "Add credit" link on My Account page) before your monthly charge - then the charge will be subtracted from your credit.
