Which file format are you using for Access (mdb or accdb)? If you are using accdb then it is no surprise it has a problem because Crystal Reports 8 had no clue about an accdb file. So, were you trying to connect to it using OLEDB? If so, you might try using an ODBC connection as that might be able to happen since the newer ODBC driver for Access would have the ability to connect with an accdb file.
