ODP.NET

Friday this was working but today it isn't and I have no idea why.
In Visual Studio 2010 I have a web application with Master page (VB.Net). I have a reference to the ODP that points to this dll: C:\app\oracle\product\11.2.0\client_2\ODP.NET\bin\4\Oracle.DataAccess.dll.
Intellisense finds this just fine and pops up the various layers as I type. When I compile it kicks no errors. When I run in debug I get this error message:

Server Error in '/' Application.
