Won’t open

I’ve been enjoying Wunderlist for a few years now. However after updating to the new 3.4.3 version it refuses to open on my Mac running El Capitan. I even uninstalled and reinstalled. I contacted Wunderlist’s customer service which was completely uesless; they advised me to access the app through another device. Thanks, but I need it working on my Mac and I don’t like the web app. Guess I will be saying goodbye to Wunderlist and move onto something else.
