Json.NET decode multidimensional array

I am a newbie in .Net and I am creating a desktop application to my website. I am passing data using JSON and Json.NET However I am receiving an error every time I try to decode this string. What could possibly be wrong? How do I decode a multidimensional array.

This is the string I am decoding

{
   "api_ver":"1.0",
   "request":"user-account-exists",
   "date":"2014-08-25 09:57:16",
   "data":
   {
      "user_account_exists":1
   }
}

My code is here

json_data = string.Empty;
try
{                
    json_data = webclient.DownloadString("http://api.mysite.com/?ruser-account-exists");
}
catch (Exception e)
{                
    Logger.Log(e.Message);
}

_api = !string.IsNullOrEmpty(json_data) ? JsonConvert.DeserializeObject<api>(json_data) : 
                                          new api();

The error is as shown below

Error reading string. Unexpected token: StartObject. Path 'data', line 1, position 86.

I want to deserialize this array into a dictionary

Try This ?

public class api
{
    public string api_ver { get; set; }
    public string request { get; set; }
    public string date { get; set; }
    public Data data { get; set; }
}

public class Data
{
    public int user_account_exists { get; set; }
}

api apiObj = JsonConvert.DeserializeObject<api>(json_data) ;

This error occurs because the api class does not model the json sufficiently.

The model should resemble the following one (generated using Json2CSharp):

public class Api
{
    public string api_ver { get; set; }
    public string request { get; set; }
    public string date { get; set; }
    public Data data { get; set; }
}

public class Data
{
    public int user_account_exists { get; set; }
}

Optionally you could use dynamic 

dynamic values = JsonConvert.DeserializeObject<dynamic>(json_data);
bool exists = (int) values.data.user_account_exists == 1;
