Visual Studio 2012 C# and SQL 2008 SP2

I'm running VS 2012 C# and SQL 2008 SP2.  I'm getting an logon error in my Crystal Report Window Forms Viewer "Logon Failed".  The report prompts the user to enter the logon information.  Some reports work some don't.  I'm using the following code to access the my database.

myReport.SetDatabaseLogon(ReportingUserId, ReportingPassword, ReportingServer, ReportingDB);

the error pops up.  I've also tried:

Tables tables = reportName.Database.Tables;

foreach (CrystalDecisions.CrystalReports.Engine.Table table in tables)

            {

        TableLogOnInfo tableLogInInfo = table.LogOnInfo;

                tableLogInInfo.ReportName = "Bill of Sale";
                tableLogInInfo.ConnectionInfo.ServerName = ReportingServer;

                tableLogInInfo.ConnectionInfo.DatabaseName = ReportingDB;

                tableLogInInfo.ConnectionInfo.UserID = ReportingUserId;

                tableLogInInfo.ConnectionInfo.Password = ReportingPassword;

                table.ApplyLogOnInfo(tableLogInInfo);

            }

Any help would be great!
