The underlying provider failed on Open - Kigg Project

Question

I have downloaded Kigg Asp.net Starter Kit Project.

I then converted it to VS.Net 2010 Project, It did everything successfully.

I then run create kigg database and also added default data. (From the script file which comes along with source)

My Dev Environment - 64 bit Win 7 OS, with VS.Net 2010 and SQL Server 2008

But i am still getting this error.

The underlying provider failed on Open.

"A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"
