Unable to log in Amazon Mechanical Turk

Hi,

I get the following error when I try to login to my MTurk requester account with my AWS credentials (as an IAM user): "✖Sorry! Unable to log in We currently do not support the country you are logging in from. We're working hard to make MTurk available for more Requesters. For the list of supported countries, click here."

The login information is correct, since I am able to login to the aws.console.amazon.com page. This is my first time that I use this account with MTurk. Any suggestions on what could be going on here?

Thank you very much in advance!
