You are unable to download/purchase because of "region" errors

I’m getting “region” errors
In order to have the best experience on the marketplace, make sure that your account region and physical location match. Your account region was set when you first created your Gamertag and can be checked by going to https://billing.microsoft.com and clicking on “Personal Information”.




If your account region no longer matches your physical location, you would have to create a new account to reflect your location. If you don’t currently live in a LIVE supported region then you may continue to experience issues with purchasing or downloading from the marketplace.

I really shouldn’t be getting these errors.
Are you sure? Positive? 100% certain that you don’t fall into any of the scenarios listed above?

Yes!
