Crystal report opening error "Server not yet opened"

HI GURUS,
I am using VB6 , CrstalReport8.0, SqlServer Version 7.0 for my application. I am using Crystal Report Designer in my project. When I am connecting to the server using Crystal Report Designer Wizard, i am able to create one designer file. When i tried to run this designer using my form file i am not able to run.
The follwing error occured. Error is "Server not yet opened"and no help message is coming. But my server is still running. Sqlserver agent is also started. Please can you give any solution for this. What could be the reason for this.
Thanking you,
V.K.GNANESWARAN

From my experience, this usually means that connection to database hasn't been successfully established.

Please check whether the datasource is set durin the run time

ie an eg
dim report as new crystalreport1
dim Myrecordset as new ADODB.Recordset

......

report.database.setdatasource Myrecordset
