Well, I downloaded the big source file before your post and tried it out, it’s OK~ So I think there is something wrong at your side or during the download? Please try to download again to prove/trace the problem.
On the other hand, even I can donwload it, but I found the artwork of the designer is really great & complicated…. that’s why I found the source file useless to me. In fact, I just want to change the background in the header area into pure white color, and actually the banner in the header area is composed by lots of pieces of layers… so I just go to the JA Business folder and found out the “output” image of the banner, then create a new banner in white color with the same dimension.
(What I expected is the psd file for the output “whole” file for the different area… but obviously I am wrong… the source file provided by JA is really a raw material~) :((
