title: it seems too many emulator instances are running on this machine. Aborting
body: <p>When I run it from the SDK manager, the loading process works, but once it is done, a flash of the emulator appears then quickly disappears.</p>
  
  <p>Sometimes after it loads, nothing happens.</p>
  
  <p>At the worst when it loads, I get the "too many emulator instances are running on this machine. Aborting" message.</p>
  
  <p>I want to start making apps, but this seems to be the only thing stopping me!
  I had already turned off Windows Firewall.
  pl'z, give me solution 
  Eclipse Indigo; r12, Windows 7 (64)</p>
