Widget Title

Hi. We recently upgraded to the Pro version of WP News and Scrolling Widget which works fine. My problem is that in the non-pro version I was able to edit the widget-title to become a link by editing the H4 tag in widget-function.php. With this new pro version I can no longer see this file and there is no mention of “widget-title” in the source code when I search the whole pro directory. Could you tell me where the widget is calling this title from so that I can edit the php file and create a link from the title again please (as this is not a feature in the widget as far as I am aware)? Thanks
