Trouble with "mock up" smart objects

[DutchyGabbana]

Ok, i downloaded this cd album cover mock up psd, and i read the instructions that it comes with....Now here is a screen shot of it, My problem is that i cant get the artwork to show up on the cd mock up. I double click the smart object and it pops up as a new doc..which im supposed to edit, i put my own artwork in the new doc and pressed ctrl + S and its updates the smart object, but it turned White??? It never updates with my art work, it just turns white????? I dont know what im doing wrong..I know someone here knows whats going on, Thanks in advance for the help, And if it matters im using ADOBE PHOTOSHOP CS 2.

Should be pretty simple just double click the layer over the CD cover area, if white is showing then you didnt put any artwork into the smart object or theres a white layer ontop.

If you have Cs5 then this is a qiuck way to take care of that or anything perspective wise.
Vanishing point.
