Cannot Add New Data Source (no replies)

Hi everyone,

Here is what I'm trying to do:

1. In Visual Studio 2010 Ultimate, I select "Add New Data Source" from the Data menu.
2. I select "Database" and click Next.
3. I select "DataSet" and click Next.
4. I click on "New Connection" and the window closes.

I've got Connector/NET 6.2.3 installed, which is the latest version according to me. I also uninstalled the connector, uninstalled VS2010, reinstalled VS2010, but the same thing happens.

Any idea why this is happening? Just reinstalled, reset settings, anything I could think of.
