Note: I apologize if I submitted this post multiple times... I've clicked on the Preview and Update buttons a few times now, but the "add post" page hasn't changed, so could only try again.
I've been trying to install the latest version of DNN Source, and my latest complication is that when I build it in VS2005, then visit http://localhost/DotNetNuke4, I get to an Installation page (http://localhost/DotNetNuke4/Install/InstallWizard.aspx) that tells me DNN is already installed. However, the "next" button is disabled (it's dimmed, and clicking on it does nothing), and when I try to visit http://localhost/DotNetNuke4 again, I get this error:
Server Error in '/DotNetNuke4' Application.

Can anyone give me pointers in where to go next?
