Gallery Not Working After Update

Now none of the galleries on my site work. There is a message displayed: “Rendering of template gallery-wp-eStore.php failed”. Please help. This is ruining my business!!

It probably just means that you need to put that template file back after the upgrade. NextGen might have overwritten the view directory where templates are during the upgrade. The templates are in wp-content/plugins/nextgen-gallery/view/

Not sure if gallery-wp-eStore.php goes in the views folder because it is an add on, but I bet it does.
