So here's the situation. My account is registered as a US account and my XBox location setting says US. I recently moved to Germany, and did not change either setting (so they still match). For the first month I was able to download DLC and the Free Games with Gold, but this month it starting saying "not available in your region." The download (Rainbow Six: Vegas free with Gold) is listed as being good in both the US and Germany, and since the XBox warns that changing locale settings may modify the wireless network settings, I didn't want to do that unless I'm absolutely sure it would fix the problem.
