Hi Paul,
Thanks for reaching out! Our Events Calendar PRO product expands upon the functionality of our core calendar offering, The Events Calendar, adding support for features such as recurring events, location-based searching, and additional calendar views. Community Events similarly extends the core feature set of The Events Calendar to add support for user-submitted events, so you can receive and manage event submissions from your site visitors.
If you believe that you’ve purchased the wrong product by mistake, we’d be glad to sort that out for you. Simply fill out our refund request form, and we’ll take care of the rest. 🙂
Thanks again, and let me know if you should have any other questions!
