I am not certain which forum would address this, so I am unsure if this is the appropriate forum.

I have lost the ability to create a dataset using the Add New Data Source in the Data Sources window. Whenever I make an attempt a connection is created in the settings tab of the project window. Additionally, the dataset shows up in the Project. What occurs is that I get an error stating
Could not get type information for 'MasterBase._MasterBase2_0DataSet',
and the dataset is never displayed in the window.

I am not completely ruling out something outside of the database (Access) and/or Visual Studio as the problem, as I have lately been experiencing other instances of odd behavior with my system. However, barring some accidental setting I have changed in either Access, or Visual Studio, is there something that I can do to correct this issue?

This is a newly created database and a newly created project.
