I see Error Logon failed...incorrect log on parameters. Did you try database->verify database?

Or, take a look at this. Does it sound familiar? Crystal Report: Unable to connect incorrect log on parameters

If there are sub reports in this report, then you must explicitly set the datasource for the sub report too. Just setting the entire dataset to main report datasource is not enough.
