PEN will act as a 30-day trial version as long as it hasn't been activated using an activation key. After this 30-day trial period, PEN will stop working. You can purchase an activation key for only $5! For now, you can only pay through RegNow or PayPal. If you order through PayPal, I will send an activation key to your email address within 24 hours (max 48 hours in the weekend) after your payment has been received. If you order through RegNow, you get an activation key instantly!
