Voice recognition with easyVR - bridge problem

Hi guys !

I'm working on a vocal recognition with the shield easyVR 3.0. I got both, shield and module.

Actually, I added the easyVR library in the arduino program, and upload the bridge example to my board. I guess that my shield is well plugged with my arduino, I saw some tutorials like this :

So when I uploaded the bridge example in my arduino, this is what I got in the serial monitor :

"---
Bridge not started!"

As I saw in the same tutorial, I tried to connect the shield with the program easyVR commander. So I chose the same COM as my arduino, and tried to connect but, even if I got the bridge example in my arduino, I always got this :

" device has been found,but the 'bridge" software is not responding or it is outdated. You need to manually download the updated "bridge" software to the device (see instructions)."

Could someone help, I don't understand anything even after many research !

If you need some pictures of how I plugged the shield and the arduino, or what I did in the program, just ask :)

Thanks
