Widgets

We are using the theme:
“Coldstone 1.0”

We had the widget “Upcoming Events” added to our page. I went back to visit the website main page and the “Upcoming Events” images that we had uploaded into the widget were gone. Underneath Appearance and Widgets I went back to add the “Upcoming Events” widget again, and when I do that and click “edit” it says “There are no options for this widget.” Is there something I accidentally disabled or something I can enable for me to allow the use of Upcoming Events? Is it just that I have no updated to 2.8 ?

Please help! I really don’t know what to do!

Thanks.
