Hi,
The site may be having a bit of trouble realising that you've updated your region, try the following:
1. totally sign out of Live.com and then back in, and try again
Otherwise:
2. delete all cookies related to live.com and mesh.com and try again
3. wait a day or so, sometimes there are very specific outages that affect pinpoint areas of the service, such as these
If after all this it still doesn't work, I would
lodge a bug, and post the ID back here - someone from the team will then follow up with you and hopefully help you solve the problem!
