Having issues with oauth token

[Rob Hayes]

I'll see if I can get enough detail in here. Please hit me with questions 
if I leave something out. I'm trying to move an application from using the 
ClientLogin to OAuth.

No matter what I do, I always get this error back from the service.
        <soap:Fault>

                    </errors>
                </ns2:ApiExceptionFault>
            </detail>
        </soap:Fault>

Code wise, all I'm doing is this. Even this I snagged from the example 
code, just because I wanted to see if something in my existing app was 
messing with things.
var user = new AdWordsUser();
AdsOAuthProviderForApplications oAuth2Provider = (user.OAuthProvider as 
AdsOAuthProviderForApplications);
oAuth2Provider.RefreshAccessToken();

ManagedCustomerService managedCustomerService =  
(ManagedCustomerService)user.GetService(AdWordsService.v201502.ManagedCustomerService);
Selector selector = new Selector();
selector.fields = new String[] { "CustomerId", "Name" };
ManagedCustomerPage page = managedCustomerService.get(selector);

Configuration wise, I'm set like this. I know it doesn't make much sense, 
given that I had to blank out so much:
<add key="DeveloperToken" value="xxxxxxxxxxxxxxxxxxxxxx" />
<add key="ClientCustomerId" value="111-111-1111" />
<add key="OAuth2Scope" value="https://www.googleapis.com/auth/adwords"; />
<add key='AuthorizationMethod' value='OAuth2' />
<add key='OAuth2ClientId' 
value='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com'
 
/>
<add key='OAuth2ClientSecret' value='xxxxxxxxxxxxxxxxxxxxxxxx' />
<add key='OAuth2RefreshToken' 
value='1/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' 
/>
<add key="OAuth2Mode" value="APPLICATION" />

I used the OAuthTokenGenerator to generate the info using the email address 
for the MCC.
