How to I fix the cd on my steepltone rock cd jukebox t?

My cd won't work on my steeple tone rock zero 50 jukebox every time I put a cd in it it keeps saying no cd and won't play! My husband just bought me it for Christmas and it has played once but when I turned it off that nite and turned it bk on in the morning it wouldn't work please tell me how I can get it to work again as I don't feel like returning it and going through the who,return saga!
