Dynamis nightmare

Can any one help me here please.

I just bought a dynamis today, got it home and decided to try it out on my length of programming track. No problems all worked well.

Then to the main track, all ran fine.

Then the green light on the receiver went out and the orange one came on constant for about 5 seconds then went out.

I now have nothing from the base unit at all no lights.

I have left it unplugged now for an hour aantried again... nothing.

Am I missing some thing or is it back to the shop?

Thanks
