I'm running the \[code\]DotNotOpenAuth\[/code\] samples, specifically the \[code\]OAuth2/OAuthClient (SampleWcf2.aspx)\[/code\] file so that it uses the \[code\]OAuth2/OAuthAuthorizationServer\[/code\] project. I'm able to authorize just fine (this is great, it's my goal) but when I attempt to get the data (like clicking \[code\]Get Name\[/code\], \[code\]Get Age\[/code\]) raises a \[code\]System.ArgumentException\[/code\] saying \[code\]"requires private key\r\nParameter name: signingKey"\[/code\].
