Maybe you could help me.
I double click on the HM3 icon to open up. It asks me "Do you want to allow this app to make changes to your device?" I hit Yes. Then little window comes up as usual (Initializing...) It disappears and nothing opens up.
My HUD is working however. I have windows 10 pro.
I tried, Run as Admin, too. No avail.
Reinstalled. No effect.
