Why doesn't my gamepad work with ue4 anymore?

I load up the basic 3rd person template (for desktop max quality with starter content) and my gamestop brand xbox controller doesn’t work. It worked fine with 4.10 and works with other programs. I’ve tried enabling input and taking it out and replugging it and restarting but I don’t know what else to do. Mouse and key input works. Please help?

Also play works but when I try to launch it gives me the unknown error!

updating windows 10 fixed the controller issue :smiley:
