Setting database path at Run-Time for Crystal Report

[Shafan]

Hi,
I've designed a report based on a ADO database using a connection string. While building the connection string I pointed out the database from which the data is extracted.
The report runs on the development machine no problems, but when I try to run it on a deployment machine I get a Database Error:
"[Microsoft][ODBC Microsoft Access Driver] '(Unknown)' is not a valid path. Make sure the path name is spelled correctly and that you are connected to the server on which the file resides".

I pass an ADO recordset to the report so I'm no sure why the report tries to look for the database where it was at the design stage.

My question is: how can I set the database's path at run time (or how do I get rid of the error)?

Thanx
