title: Cucumber and Watir suddenly stopped working
body: <p>I have been using Cucumber all day and even though I did not change any files, it just stopped working. </p>
  
  <p>It gives me an error that reads: </p>
  
  <p><code>Unable to either launch or connect to Chrome. Please check that ChromeDriver is up-to-date. Using Chrome binary at: /Applications/Google Chrome.app/Contents/MacOS/Google Chrome (Selenium::WebDriver::Error::UnknownError)</code></p>
