[Plugin: Visual Form Builder] Error After Upgrade

Hi all,
I have just upgraded from free version to pro. But when I click on Edit it shows this error :

Fatal error: Call to undefined method WP_Screen::get_columns() in /home/user/public_html/wp-content/plugins/visual-form-builder-pro/includes/admin-form-creator.php on line 49

Anyone have any solution for this, please ??
