Vexilar review for My Product Registration

Doesnt install. Have tried on numerous browsers and many attempts. The app installed once and timed out over and over and over again, so I uninstalled it. Since then, it continues to not install across Firefox, IE, Safari, and Edge. Across 4 different storefronts. I wish I could contact you but again the APP DOESNT SHOW UP. DROP ME AN EMAIL I CAN CONTACT AND ID BE HAPPY TO TRY AND WORK THIS OUT. They fixed the problem they claimed in their response, for about 3 days and now again this app won't load on Safari or Edge. Businesses don't have time for apps that don't open.
