I had this problem last month (and started following this thread just in case), but the only thing that got me past it was to submit a request directly to Minecraft. Go to Minecraft.net, select "Support" and then click on "Contact Us" at the bottom of the page. After that it took about a day for them to get back to me and resolve the issue. I think this is something that needs to be adjusted on their end. Frustrating, but fixable. Good luck!
