Hi - We added some features within the updated releases for full support against 5.6.x and DNN 6.2.x. You will need to be running on the 4.1 release for full support against 6.2.x because of these email updates. Let me know if you have any other questions. You can find our full upgrade policy at
http://www.datasprings.com/upgradepolicy or if you open a support ticket and let us know your Invoice ID we can check to see what discounts might apply for your previous purchase.
Thanks,
Chad
