ReportSmith connecting to Oracle: ERROR

I first installed Delphi 1.0 and ReportSmith 2.5 on my PC. Everything
worked out just fine. Later I tried installing Delphi 2.0 and ReportSmith
3.0 over Windows95. My database is Oracle 7.2. Delphi's connection is
O.K. but when I try to connect using RS, I get the following message:

"Unable to load database access DLL"

I tried renaming ORA71WIN.DLL to ORA7WIN.DLL, but it didn't worked out.
Later I tried renaming ORA72.DLL to ORA7WIN.DLL and it didn't worked
out. ORA72.DLL is the file used as vendor init in Delphi 2.0 connections
to Oracle.

Does anybody know how to fix the problem? If so, please let me know as
soon as possible.

Thanks.
