sp_configure?

What is this?

I am trying to connect to a SQL Express .mdf file via VB Express 2008, and i'm getting this message:

"Generating user instances in SQL Server is disabled. Use sp_configure 'user instances enabled' to generate user instances."

Now i know some about databases, but mostly from the front end not the back end, so I'm a little slow on the uptake when it comes to setting these things up. I've managed to set up SQL Server Authentication and everything and can log in with an account access or with Windows Authentication, but both times, I set up the Data Connection in the Database explorer, browse for the file, and try to test the connection and get that message. What does that message mean? Where is that setting?

Thanks

See kabalwegs answer in thread Enable User Instances in SQL Server. I haven't tried it since my SqlX already was configured for user instances, but it sounds right.
