K8 Stinger Store review for Product Page Banners & Text

Love the app, but I cannot reach the developer at all. My email sent to [email protected] is bounced back immediately, because the domain productpagebanners.com couldn't be found. Seems like this app was abandoned. I downloaded the app and installed it, was able to set up 5 banners, and I cannot add any more, please help!! Love this app and would like to use many more banners, but I cannot until I hear back from someone!
