Google DoubleClick Implementation for iOS

I downloaded the Google DoubleClick SDK for iOS and am plugging it into a project. Within the SDK download there is a demonstration project named DoubleClickExample which builds without issue and executes. However the test credentials it utilises do not seem to generate ads. Instead, the delegate method loadFailed is called and I get the following error message:

Load Failed: Error Domain=com.google.ads Code=5 "Request Error: No matching ad" UserInfo=0x6331de0 {k=sdktest/testing;k开发者_StackOverflow社区w=test, color_bg=FFFFFF, NSLocalizedDescription=Request Error: No matching ad}

The Code=5 seems to be a SOAP error code - source

You are not authorized to perform this operation.

Has anyone...

a) encountered the same issue?

b) managed to overcome this in a test environment?

c) managed to overcome this with a real active DoubleClick account?

I do not have a DoubleClick account as I am implementing this for a client so I was genuinely hoping that the out of the box test code would function.

I'm currently building under xcode 3.2.6 for the sake of the current code base but I have compiled the DoubleClickExample under xcode 4 as well, with the same result.

Any help / guidance would be much appreciated.

Did u know that

In order to show DoubleClick ads, you must have an active DoubleClick Mobile account
