Ok thank you. Also in the readme.txt there is the following instruction:

4) Replace the query in your query window with this code and press F5 to run it - please
   make changes to the user credentials first - NEVER use the same username and password
   as those that come from a book or Internet site:

USE TheBeerHouse
GO
EXEC sp_addlogin 'DBuserName', 'SecretPassword', 'TheBeerHouse'
GO
EXEC sp_grantdbaccess 'DBuserName', 'DBuserName'
GO
EXEC sp_addrolemember 'db_datareader', 'DBuserName'
GO
EXEC sp_addrolemember 'db_datawriter', 'DBuserName'
GO
EXEC sp_addrolemember 'db_owner', 'DBuserName'
GO

 am I supposed to run this query on the database aspnetdb? Thanks
