Error: database connector 'crdb_ads.dll' could not be loaded

I have written a report using CRXI professional. I have downloaded the trial of CRXI Developer, and installed it. When I open the report run it I get this error:

Failed to load database information. Details The database connector 'crdb_ads.dll' could not be loaded

I am trying to connect at an advantage DB, on a linux machine. FYI, the report worked on a different machine using the professional edition.

Any help????
