Hi @masstaxschool
Thank you for using our plugin.
We apologize for the inconvenience.
If you are using the plugin free version, then updates comes from wp.org and it is working fine.
If you are using the plugin pro version, make sure that you have entered your license key in the plugin settings. After saving the license key in the plugin settings refer to the plugins update page on your site admin area and click on “Check for updates” link then try again.
Just please make sure that your license key is not expired for the pro version.
I hope it helps.
Best Regards
