My son just opened his controller yesterday and it only had the controller and connector for the computer. There wasn't any software or instructions. We got the software of the website and loaded the controller only to find that the RT2 button was stuck. We managed to work around the button to set it up for a few different games. Now in doesn't work at all. It won't load any macros and the LED light is not working to tell you if the controller is on or not. Tried brand new batteries. How do I send this back to be repaired? We just opened it yesterday!
