Default Chapter 10 exception error

When trying to run the program after completing chapter 10
I get the following error message:

An unhandled exception of type 'System Exception' occurred
in WroxDataAccess.dll

Additional information: object reference not set to and
instance of an object.

I've went over everthing several times and don't have
clue to what the problem might be.

Thank you (anybody) for any advice you may have.

I got it so that the above error message no longer
occurs, however now I get a message box that says
"SQL Server does not exist or access denied"
I'm using MSDE and
I know the server is there because I have tested
the connection to the server and the database via
 the Data link properties window using NT integrated
security.

help please?
