Cant seem to download pattern

OKAY- so this is a problem only with firefox - DOES anyone knows how to fix this??

Hi!

Ive tried to buy and download two patterns today
Ive clicked on the paying button, and then when I click to download the PDF nothing happens!
The Capybare gives me a blank page, and with the cloud there is an small PDF file wich downloads but computer says there is a part missing (and its 3 bytes smal...)
Both are now at my "ibooks" link. Ive clicked more times, so I hope it doesnt charge me with all the extra "download" click costs.

Thanks in advance,
Here are the patterns Im talking about:
