When I make my crystal reports viewer running on Win7 refresh, I get this. in the CrystalReportsViewer control in my Winforms Application. Additionally, if I update a parameter in the report like this....
ReportDocument myRpt = new ReportDocument();
myRpt.Load(crReportFileName);
ParameterValues pvValues = new ParameterValues();
ParameterDiscreteValue pdvDiscreteValue = new ParameterDiscreteValue();
pdvDiscreteValue.Value = 1500603;
pvValues.Add(pdvDiscreteValue);
myRpt.SetParameterValue("Select_JobNo", pvValues);
crystalReportViewer1.ReportSource = null;
crystalReportViewer1.ReportSource = myRpt;

Blank info means the info you are passing is either not correct or the DB client is not installed or cannot be found.
Try using the IP address or if it's ODBC then make sure the DSN is a system DSN and the 32 bit ODBC admin is used to create the DSN.
Test using a single table/field report first.

I assume you are using CR for VS .NET SDK.
Only reason it prompts for more connection info is either the code you are using failed to log on the main and subreports or missing/wrong parameter values.
Latest .NET SDK is from here, SP 20.
