Emulator Enhancer: can't interact with 'Register' popup

Emulator Enhancer is a shareware product. Would you like to register now?

I try to run nestopia, but I’m asked to register ‘Emulator Enhancer’ - or at least defer to later. How can I do this without the use of a keyboard? The Apple TV remote doesn’t interact with the popup menu buttons (Reinstall/Maybe Later/Yes Please).

Eventually the Apple TV restarts, but you can’t back up out of the menu either.
