Fatal errors in all my WP sites with WPDM Extended Short Codes Add-on

Recently I’m receiving fatal error advices in all my WP sites using WPDM + WPDM Extended Short Codes when trying to access Plugins or Updates sections. The advice identifies WPDM Extended Short Codes as the cause of the error.

Here is the error I receive:

An error of type E_ERROR was caused in line 439 of the file ***********/wp-content/plugins/wpdm-extended-shortcodes/wpdm-extended-shortcodes.php. Mensaje de error: Uncaught Error: Call to a member function getLatestVersions() on null in ***********/wp-content/plugins/wpdm-extended-shortcodes/wpdm-extended-shortcodes.php:439

Hope it can be soon solved with an update.

I’ve subscribed to a previous thread about the same problem. Sorry for posting before searching.
