Hi Imar,

I'm having a problem opening PlanetWrox.mdf.

I copied the database over to App_Data, then double-clicked on the database.
Server Explorer appeared and shows PlanetWrox with a red symbol on it. I click on it and I get the message 'Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.'

Any idea how to get this working?

I have SQL Server Express 2008 R2 installed.

Regards

Hi again,

I uninstalled every SQL, and reinstalled SQL Server 2008. Now working.

Relief! :)

Regards,
