problems with VB6 prof. and crw OCX with Access2000

[smoky2]

I am working with VB 6.0 Prof. (German) SP6 and Crystal Report OCX (CRW32 4.6) wich was included
Since many years our bookkeeping programm is running fine using appr. 30 different print masks (name.rpt) and the following procedure.
CrystalReport1.DataFiles(0) = database
CrystalReport1.ReportFileName = print mask name.rpt"
CrystalReport1.Connect = "DSN= ;UID = ;PWD = database passwort;DSQ= "
CrystalReport1.Action = 1
If data are stored in Access97.MDB and the PC is running with Windows98, everything is ok.
1. Problems occur if data are stored in Access97.MDB and the PC is running with WindowsXP, having installed OfficeXP
2. Problems occur if data are stored in Access2000.MDB and the PC is running with Windows 98 or WindowsXP.
If I am working within Crystal Report, there is a possibility of using ODBC Driver but I have to build a new Print mask.
Who knows, how to solve my problems?
Is it possible to update the Crystal OCX?
Is the problem solved, if I update VB6 (which version is necessary)?
Is the problem solved, if I update CRW32 4.6 (which version is necessary)?
I would appreciate any help and thank you in advance. Excuse my English, I tried my best.
