I have an expired license to JomSocial 3.2.1.2. I want to upgrade to the current version 4.2.1. What is the cheapest/easiest method to do this? I see a 35% off professional renew/update - how do i go about receiving this discount?

Hi Mike,

You can renewal from "My Account" page www.jomsocial.com/component/digistore/licenses , click "Renew" and then the price will be automatically discounted.

I hope it will help :)
Cheers!
