Hi Nick, My guess is that either you don't have an app.config, or the library is not picking up the AdWordsApi section from app.config. This shouldn't have been an issue though, but a check that I added at http://code.google.com/p/google-api-adwords-dotnet/source/browse/branches/v11.0/src/Common/Lib/AppConfigBase.cs#227 is throwing up the error. To fix this error, you have to change the code like
if (settings == null) { return defaultValue; } else { return settings.ContainsKey(key) ? (string) settings[key] : defaultValue; } Could you open an issue at http://code.google.com/p/google-api-adwords-dotnet/issues/list so I may track and fix it? Cheers, Anash P.
