Tech is passing me by

I have been trying to play Minecraft with the kids. I love the idea of playing, exploring and building and fighting in a shared world, it's basically the dream. But in practice I absolutely cannot get it to work reliably. I am starting to wonder whether I'm turning into the 21st century equivalent of middle-aged people who need to get small children to program the video recorder for them!

Halp?!
