请教RDA与sqlserver数据同步问题（急）

我的环境是：sqlserver2000+sqlce3.5+sqlcesa3.5+vs2008
在进行测试时我采用了以下方法：
  C# code:

SqlCeRemoteDataAccess access = new SqlCeRemoteDataAccess(@"http://localhost/sqlce3.5/sqlcesa35.dll", @"Data source=MyTest.sdf");
string ConnectStr = "Provider=sqloledb;Data Source=127.0.0.1;Initial Catalog=MyTest;User Id=sa;Password=sa;";
access.InternetLogin = "";
access.InternetPassword = "";
access.Pull("person", "select * from person", ConnectStr, RdaTrackOption.TrackingOnWithIndexes,"errortable");



然后出现以下异常，详细信息如下：
C# code:
