Problems migrating from VS2008 to VS2010

I have an application developed with VS2008 that works perfectly.with many CR's. It uses an ADODB connection to an Access database. I tried a conversion to VS2010, but it does not work as any time I try to display a report the followinf dialog appears and there is no way to connect to the database.

Can anyone help me to solve the problem? I looked around in the web, but non of the proposed solutions seems to apply.
