Crystal Reports and Sql CE

I have created a desktop application using SQL Server and I now want to switch it to SQL CE so that it can be a stand alone app. No problem converting the code, that works fine but  I am going crazy trying to get my reports to use the embedded database.

So far I've tried:

1. Go into report and choose Set DataSource Location then find my dataset under ado.net objects.

2. Go into report and Set DataSource Location then find my dataset under Database files.

3. Create a dataset in code and assign it to the report's datasource property.

4. Create a new report using the dataset.

None of these returns any records.It's like the report can't connect to the database.

Any help with this will be greatly appreciated.
