Titanium doesn't launch android emulator

Hello,

I'm new on Titanium and i've a first problem. I just want to launch the android emulator for test the default app 'Hello'.

But when i click on run (with titanium_1_WVGA800 option), nothing happens.

In menu Preferences, i can launch the emulator by the manage avds button but my app doesn't exist.

Do you know the issue ?

Thanks.
