Aaah, so you're in a different region than the account or card? I'm afraid that'll do it, yeah. Here's what you could do: if your account is set to Spain and you are in Spain, you could try purchasing MSP through a retailer and make the purchase that way.
You'll just want to make sure you have your account set to the right region, or there could be other purchasing/downloading issues.

Here's info on doing that:
Change the Region of your Xbox LIVE Account

Tried a couple of different cards, same problem. I think it's my IP being in Spain, although I have a US military address associated with my card. Kind of sucks that those in the military overseas can't download due to restriction in place based on the
IP address.

fix the problem

Try deleting the game from your hard drive and any non essential saves (if any) and download the game again

You could also try deleting any dlc as this has caused a couple of issues in the past, the content can be reinstalled when your game is up and running by viewing your purchase history.

Finally try the old favourite of clearing you cache as below:

Could you all please go ahead and follow
THIS guide (clearing your cache) and then seeing if the problem has resolved. If that helps, then great! If not, please create your own threads and detail your problems in there. Users are encouraged to create their own threads, so that the focus of support

@WizZz27 could you also please try the above steps and let me know (In this thread) whether that has resolved the problem?
