I just started getting this warning 20 minutes ago. "Warning: This Is An Invalid Box!!!" would pop up on screen whenever I changed channels, so like a dumbass, I reset the unit before checking these forums and now I have a new brick to play with

It's been running perfectly fine for 2 months and I haven't changed anything, so I'm confused as to why it would just pop up out of the blue.

After doing some research I can confirm that it is definitely a genuine box, so at least I know I haven't been scammed by the retailer (cablebox4u.co.uk). Luckily for me, the box is still under warranty, so I've sent them an email detailing the problem and hopefully they will sort me out.
