Another “This domain name can’t be used because it contains a protected word or inappropriate language. Please contact support if you feel this is not the case.”

Hi I'm also getting the message "This domain name can't be used because it contains a protected word or inappropriate language. Please contact support if you feel this is not the case." when trying to register a domain on the Live Admin Center.  The domain I'm trying to add is saovietcomposites.com we are a small manufacturer of composite products.  I appreciate any help getting this to work.
