Hi Carlos,

I notice that your KEY_LOCATION points to a pem file. Are you sure this
pem file matches up with your KEYPAIR on Amazon? Could you double check
that you're able to launch and connect to an instance using that pem
file manually using ElasticFox or the AWS Management Console?

Thanks,

~Justn
