It seems that everything is ok now.
The license is active “Status: active” and the plugin is updated even if a few steps before, when I try to update the plugin, it shows me a denied access error.
Thank you anyway.
We bought an extended license to be able include it in our theme, and we own only one license key (as well as in case with single license), theme buyers are not allowed to use that key. But, don’t worry, Plugin Elementor Pro still working in your site.
To update new version, please deactive current plugin, download new plugin at http://source.wpopal.com/plugins/new/elementor-pro-3.x.zip and re-install
