Adwhirl test ad issue

In my application i have integrated ad-whirl, in the ad-whirl setup i have configured 3 ad networks like iad, ad-mob and Millennial Media but ads are coming only from ad-mob network. Even i have turned off both iad and ad-mob network in ad network setting in ad-whirl.

I have integrated all the 3 ad network sdks

And i have returned this code in adwhirlViewController

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:YES];

    adView=[AdWhirlView requestAdWhirlViewWithDelegate:self];

    [self.view addSubview:adView];  
}

- (void)adWhirlDidReceiveAd:(AdWhirlView *)adWhirlView {
    NSLog(@"Ad received");
    CGSize adSize = [adView actualAdSize];
    NSLog(@"Net work Name %@",[adWhirlView mostRecentNetworkName]);
    CGRect newFrame = adView.frame;
    newFrame.size = adSize;

    newFrame.origin.x = (self.view.bounds.size.width - adSize.width)/ 2;

    newFrame.origin.y=385;
    NSLog(@"frame size %f,%f",newFrame.origin.x,newFrame.origin.y);
    adView.frame = newFrame;

}

- (NSString *)adWhirlApplicationKey {
        // return your SDK key  
    return kSampleAppKey;

}

-(void)adWhirlDidFailToReceiveAd:(AdWhirlView *)adWhirlView usingBackup:(BOOL)yesOrNo
{
    NSLog(@"Ad not Received");
    NSLog(@"Net work Name %@",[adWhirlView mostRecentNetworkName]);
    CGRect tempFrame = adView.frame;
    tempFrame.origin.y = -adView.frame.size.height;
    adView.frame = tempFrame;

}

But ads are coming only from admob. please guide me to fix this issue.

Thanks.

What SDK key does kSampleAppKey map to? Are you sure that it maps to the key given to you by the AdWhirl console when you set up your ad placement?
