*scratches head*
When I log in (using my Live.com account), gamesforwindows.com shows "US" and I can't change it. If I log out I can change it here:
http://www.gamesforwindows.com/Resou...International/
There's no Spain available. The only problem is when I have to enter the billing address, the country is set to US and can't be changed there. I've been all around the website as well as Live.com and other MS sites, I've changed a couple of things, but it doesn't seem to affect gamesforwindows.com.
I've probably made some mistake, but MS could have made it easier. I don't know if I'll contact support...
