I'm trying to make a desktop app with C#. I have the following but when I call auth.UpdateCredentials() it fails with "Unknown error". I changed the numbers of the id, secret, and token. These are not the real values. I guess the reason I'm showing some values here is because in the source code it says token, but when I got my information it was called API Key. Just wanted to make sure they were the same thing.

CODE

// Enter your application ID here.
            String appid = "MWMIti5c";

			// Enter your shared secret here.
            String secret = "bew4c13cd1c88ae3e0h4153524d1ce90h0d332bw";

			// Enter the user token here.
            String token = "yj0yJmk1YWFuRWVTdzFKUzVWJmQ9WVdrOVRWZEWTWFJwTldNbWNYbzlNAFl3TlRjek5UZy0tJnM9
Y29uc3VtZZWNyZXQmeD1jMA--";

			// Get the auth credentials. Create the Yahoo.Authentication object with the 
			// application ID and secret from the BBAuth signup process.
			Yahoo.Authentication auth = new Yahoo.Authentication(appid, secret);

			// Set the user token.
			auth.Token = token;

			// Update the credentials. This will fetch a new WSSID and a "Y" cookie for 
			// the user.
            try
            {
                auth.UpdateCredentials();
            }
            catch (Exception e)
            {
            }
