Do you have to return the whole package to argos?

I got a wii fit on monday and another fitness dvd for it. With the wii you get a dvd with it as well.

The wii board works, but the dvd that came with it doesn't. Cant for the life of me get it to work. But every other game will load.

Can i just bring the dvd back and get that exchanged or would I need to bring back everything?

I was a bit silly in opening it......think of a child on christmas morning!!

Best bring the whole lot back, I wouldn't worry too much about the packageing as you only want to replace the dvd,their pretty cool in argos.
