Nothing happens when I’m trying to press “Launch” in the emulator manager in order to launch the Wearable-2.3.1-circle emulator. I’ve read the emulator manager’s logs but I can’t understand the reasons of this failure. There are these logs:

I would be very grateful if someone would help me solve this problem.
