title: Sensor Emulator in Android freezes ! WARNING: Unable to create sensors port: Unknown error?
body: <p>I'm using the Sensor Emulator from OpenIntents. I got 1 or 2 times to run the emulator on my pc but after that due to some errors in my program the Sensor Simulator stopped to work, the program simply freezes when I'm trying to start up the Sensor Emulator Library. An Android SDK new full installation or either a fresh Sensor Emulator installation doesn't solve the problem.
  When I start the Android Emulator in DOS mode it says: WARNING: Unable to create sensors port: Unknown error.
  On other Pc's this error doesn't appear and I assume that this error even when the Sensor Simulator worked didn't never appear. Any suggestions about how to get the Android Emulator to properly work again with the Sensor Emulator ??
  I'm using Windows 7 Pro.</p>
