Unable to find the requested .Net Framework Data Provider. It may not be i

I am creating a new dabase application using VS2008, c#, Oracle 11 database, and Oracle 11g ODAC with Oracle Developer Tools for Visual Studio. The database server is running win32. The developing computer is a 64bit processor running win32. I am getting the following error: "Unable to find the requested .Net Framework Data Provider. It may not be installed."

I am able to retreive and update data using a gridview with no problems as long as they are text, date columns, or hardcoded (text and values typed directly into the aspx page) combox columns. If I change the comboboxcolumn and point it to a DataSourceID and put it in edit mode I get the above error. If I add a combobox directly to a form and point it to the same DataSourceID and run the form the data displays in the combobox and can be selected. Everything I find concerning this error points to making sure the web.config and machine.config file are updated. I believe mine are. Do you have any suggestions:
