title: Build failed! message, can't build apk in App Inventor
body: <p>I'm currently working on a bit bigger project in app inventor. I basically finished it, and have had no problem downloading the apk. Just wanting to change some information however, I can no longer download the apk. Also trying to download old saves doesn't work. Much smaller projects is working however.</p>
  
  <p>The trouble message I'm getting is "Build failed! Can not contact the BuildServer at buildserver.appinventor.mit.edu"</p>
  
  <p>Now on my third day of trying, without success.</p>
  
  <p>Anyone no whats going on?</p>
