Casio CZ/ VZ/ FZ - Pro Series

Hi,

I have some trouble to download the "powerplay" files.
I tried out several browsers.One is hanging at the 81% mark,and
the oothers download it complete,but when try to open,Acrobat Reader
says,that the file is damged and can not be opened.

Anyone else who had such trouble ? 

Or is it my Mac,wich wants to tease me to Face Distortion ! ,)
