I have tried to download Freya on a Linux machine using Chrome and Firefox, I also tried to download it in Incognito / Private browser modes.
I have also tried on a Windows 7 machine using Chrome and Firefox. I did donate (twice) but when I click on download the screen goes grey.
Is this because I am trying to download from the UK? I see that the store only accepts US orders.
On an earlier question posted by someone else ( I am unable to download elementary OS ) you posted links to a direct download - I tried to follow them but got the message "405 Not Allowed".
