Reports quit working after upgrade to SQL Server 2008

Question

Folks,
I'm running Visual Studio 2008 (sp1) and recently upgraded to SQL Server 2008. Reports worked fine until after upgrade. Now I get the "Login Failed" error message.
Here is code snippets:
        CrystalDecisions.CrystalReports.Engine.ReportDocument oReport = new   CrystalDecisions.CrystalReports.Engine.ReportDocument();
        TableLogOnInfo LonOnInfo = new TableLogOnInfo();
        TableLogOnInfos crtableLogoninfos = new TableLogOnInfos();
        TableLogOnInfo crtableLogoninfo = new TableLogOnInfo();
        private Tables crTables;
        private Table crTable;
        ConnectionInfo crConnectionInfo = new ConnectionInfo();
            crConnectionInfo.IntegratedSecurity = true;
            crConnectionInfo.ServerName = Properties.Settings.Default.InstanceName + "
Instance";
            crConnectionInfo.DatabaseName = "DATABASE";
            crTables = oReport.Database.Tables;
            for (int i = 0; i < crTables.Count; i++)
                crTable = crTables<i>;
                crtableLogoninfo = crTable.LogOnInfo;
                crtableLogoninfo.ConnectionInfo = crConnectionInfo;
                crTable.ApplyLogOnInfo(crtableLogoninfo);
            oReport.RecordSelectionFormula = xFormula;
            crystalReportViewer1.ReportSource = oReport;
Has anyone had this problem? Any help would be appreciated.

CR 2008 does not support MS SQL 2008 yet, meaning we have not had time to test it completely and add it to our supported platforms.txt file.
One thing I noticed is you are using trusted authenication:
crConnectionInfo.IntegratedSecurity = true;
Make sure you give access to all users, MS changed the security properties a lot since SQL 2005 and you can't simply log into any database now. If you have a DBA check with that person on how to configure NT Authentication or the Help file. You can also do a quick test and simply use MS SQL Server authentication to confirm if it's a user permission issue.
Try creating a report that doesn't use Integrated Security, check the box off on your data logon prompt in the Designer.
