new KATATONIA desktop

I love your wallpapers dude, they're really great, but I've got a problem. The Katatonia "Season" one, I've tried downlaoding this about 5 times, and everytime I have I've tried to unzip it using Winzip and it's told me it's not a valid .zip file. I'm using the latest version of Winzip I just wondered if you knew any solutions.
 
I don't know, because evdry other one I've downloaded from there has worked fine and so has everything else I've tried to unzip. It might be a glitch in my downloads not getting the complete file.
