title: Gitbash closes immediately, can't sign in to Github
body: <p>I'm just getting started with GitHub and I'm trying to follow these instructions: <a href="https://help.github.com/articles/set-up-git" rel="noreferrer">https://help.github.com/articles/set-up-git</a></p>
  
  <p>I've downloaded GitBash but when I click on it, the window pops up for a split second and then disappears again. I've tried not using the shortcut, and uninstall/reinstall, but neither helped, and I don't know enough about it to do any additional troubleshooting.</p>
  
  <p>Even if you don't have a solution, some google search terms would be great - I don't know if there's a specific name for this kind of a problem. </p>
  
  <p>Thank you!</p>
