title: Windows Phone 8 MonoGame projects stopped working
body: <p>I'm not sure exactly what happen.  </p>
  
  <p>I had visual studio 2012 installed with MonoGame 3.0.1 and all the demos from the book (Windows 8 and Windows Phone 8 Game Dev) everything was working.</p>
  
  <p>However after not doing anything for a month i went back today to pick up on a game where i left off and i can no longer get my games to work. Theres a chance i upgraded visual studio or windows in between.</p>
  
  <p>I also tried upgrading to MonoGame 3.2 and that did not solve the issue</p>
  
  <p>The normal projects from the book work (the windows game demos) and a new windows phone app with the default controls work.</p>
  
  <p>I'm mostly a Linux developer so a little stumped on what could of happen with the windows phone games.</p>
  
  <p>My output when run the demo games is below, i'm continuing to look into it, but any help would be greatly appreciated.</p>
  
  <p>UPDATE:  When i say "stopped working" i mean the games compile and the emulator gets loaded but then its just a black screen.  Where as before there was animation.  Also these are the books demos, not mine.  They worked before</p>
