I'm sorry to hear that your remote control doesn't seem to be responding. I'll be happy to help out here.
Can you please let me know if you get a response from the box if you press the buttons on the front of the box itself? This will help rule out if it's a possible faulty remote control or if it's the box that's not responding.
Let me know how you get on, I'm here to help if you need me.
