Android Emulator : Device Unavailable / select device

Hello,

How can I select the device opened in the emulator. When I launch the debug, here is the pop-up I have : - Title : --------Device Unavailable - Text : --------Device : is either not running or not attached --------Available devices : --------MonoForAndroid_API_14

I did launch this device in the emulator. Where do I select it ?

Here is the installation I have made : - Install VS 2013 - Install Xamarin Ios and Android with "XamarinInstaller.exe" - Start trial in VS - Download the Tasky for Android

For your information, I had to put in the GAC the Microsoft.VisualStudio.ExtensibilityHosting dll version 11 to compile.

Thanks in advance for your help.
