The remote server returned an error: (401) Unauthorized.

Hi,

I'm attempting to use api for something as basic as connecting to my api,

var configuration = new ApiConfiguration("http://192.168.1.21:8080/AccountRight/c30568dfa-b8ea-4b30-b0f6-d549011abe27");
var credentials = new CompanyFileCredentials("Administrator", "secrete");
var cfService = new CompanyFileService(configuration);

var companyFiles = cfService.GetRange();
var companyfile = companyFiles[0];

but I get an error,

InnerException = {"The remote server returned an error: (401) Unauthorized."}

Message = "Encountered a communication error (http://192.168.1.21:8080/AccountRight/c30568dfa-b8ea-4b30-b0f6-d549011abe27)"

I've used api's for just about everything else, it's just the myob api's that are not working, and example listed in the SDK is very vague, without much help.

Can anyone offer a solution ? Thanks you.
