Logo slider (PRO) has stopped working on our website and nobody cares

We are using the PRO version of Logo Slider plugin, however, it suddenly stopped working and is no longer displaying on our website. We have tried creating a new slider, but there is always an infinite spinning loading circle where the logo slider should be. We have been trying to contact their support for months, but they have not responded! So, we are leaving this review in hopes that they will finally notice us!
