Free AC3 with GTX660

[Greenbandit]

I just received a GTX660 with a voucher for a free download of AC3. The card works fine but I am unable to get AC3 to download.

I went onto the nVidia site, entered the 6*4 code on the card, got a 9 digit promo code emailed to me, but when I go to shop.ubi.com:-
- I do not know which version of AC3 to select - which is it?
- I cannot get the promo code to do anything as each time I try to checkout I get as far as being asked for credit card details with £59.99 to pay. How should the code be redeemed?

Many thanks.

Sorted - Today it worked.

Don't know why it did nothing yesterday.
