"IP Status of tunisports.com Name Server Misconfigured - one or more name servers for this domain is not returning an IP address. Please contact the admin for the name server."
Maybe your new host hasn't associated your domain to their name servers yet. You would have to contact them to be sure. You can use the IP Lookup Tool to see the query results to the name servers. Right now they show 'none', but the name servers should be sending the ip address location to the IP Lookup Tool.
How do I access the IP lookup tool? http://www.dynadot.com/help/question.html?aid=48
