Yes, your subscription is active. Please ensure that you are using the correct subscriber ID, and not the payment ID you received from Paypal. You can find the subscriber ID on our site sourcecoast.com. When logged in here, use the My Accounts > My Profile menu item. The correct subscriber ID will be listed on the right-hand side of that page.
The subscription is valid for 6 months. After it expires, JFBConnect will continue to work on your site. However, you will lose access to new releases, support and our automatic configuration tool (Autotune) in JFBConnect.
I hope this answers your question. Let me know if you still have trouble getting the subscriber ID to work after reading the above.
