Custom MessageAdapter

I'm in the process of creating a custom adapter. After adding the adapter to the connector and attempting to configure:

 
    var gc = new GainCapitalMessageAdapter(_connector.TransactionIdGenerator);
    _connector.Adapter.InnerAdapters.Add(gc);

      if (_connector.Configure(this))
        new XmlSerializer<SettingsStorage>().Serialize(_connector.Save(), _connectFile);

The following error is produced:

  Message=Description of connection GainCapital.GainCapitalMessageAdapter not found. (Parameter 'adapter')

If added the following attributes to the custom MessageAdapter:

  [CategoryLoc("Forex")]
  [DescriptionLoc("Str1770", LocalizedStrings.GainCapitalKey)]
  [DisplayNameLoc(LocalizedStrings.GainCapitalKey)]

Also, while Unit Testing, the connect event is not firing but sending the ConnectMessage works:

      var gc = new GainCapitalMessageAdapter(_connector.TransactionIdGenerator);
      _connector.Adapter.InnerAdapters.Add(gc);    
      _connector.Connect();  //-- does not work
      gc.SendInMessage(new ConnectMessage { Adapter = gc });  //-- works

If this is included in a lesson, let me know. Otherwise, any advice is appreciated.

Thank you.
