I've am trying to access the currently logged in user's album list but i keep getting the error (500) Internal Server Error, and when I inspect the response, it tells me Invalid token.

My App is in ASP.NET 1.1 and i'm using the GData client library. I've followed the steps correctly to authorize a user and get a sessionToken in the AuthSub and GData client library documentation, that is, using the getRequestUrl, getTokenFromReply, exchangeForSessionToken, and setAuthenticationToken.

Here's the code I use: PicasaService s = new PicasaService("MyApp"); s.SetAuthenticationToken(sessionToken); AlbumQuery query = new AlbumQuery(PicasaQuery.CreatePicasaUri("default")); PicasaFeed picasaFeed = s.Query(query); //ERROR IS THROWN HERE

What am I missing? I've tried it on my local machine and my remote server but it still gives me the same error.
