Crystal Report 6.0 in VB6

Hi,
Now i upgrade one vb6 Application that talk to Access97 to Access2000 and use crystal report 6.0. But when i want to print report got error : Unable to load report and Error.Number : 20525

My coding is
VB Code:
Main_Frm.CrystalReport1.Reset
           Main_Frm.CrystalReport1.DataFiles(0) = c:\db.mdb
           Main_Frm.CrystalReport1.ReportFileName = " C:\report1.rpt"
           Main_Frm.CrystalReport1.Destination = crptToWindow
           Main_Frm.CrystalReport1.WindowState = crptMaximized
           Main_Frm.CrystalReport1.Action = 1
And in my pc i also install .net and crystal report 9.0. Does it crash with crystal report 6.0

Can any one help me. Thanks a lot
