Crystal Reports

Question

I have been able to get many different style reports to work in a browser whether I use push or pull method, but every time I try to change the 'SetDataSource' property of the report before pushing it to the viewer, I receive the following error; System.IO.FileNotFoundException: File or assembly name ADODB, or one of its dependencies, was not found. I have the most recent framework, MDAC 2.8, framework sdk, and crystal loaded on both the server and the development machine. Anybody have any ideas what I'm missing? Thanks in advance for any time spent.
