Thiago, try this
1. Go to the Line 6 website and download the latest drivers.
2. Without the Pod plugged in, install your drivers.
3. Restart your computer after installation.
4. Now plug in your Pod to the computer.
5. Open the Monkey and log in.
6. Wait for the program to recognize your Pod.
7. If it does not, try a different USB port.
8. If it still doesn't recognize your Pod, then install the next newest driver version.
I experienced times when the newest driver didn't work but the older did.
Good Luck. AZ
