I downloaded multi-bit yesterday and purchased my first bitcoins today

I have made a fatal error when I opened multi-but there was a send address of 1cxXpVHyWqpqRSbiaf849NPgaHsoBmnEH that seem to come with the software ?

Upon purchasing 0.4 bit coins i sent them to this address from the site i purchased them from.

It seems I have not used the correct address in the software,

I am assuming i sent multi-bit these coins can you kindly return them to me ?
