Cannot find my database in crystal repost database expert

Attach the MDF file to SQLExpress

SQLCMD -S.\SQLEXPRESS -e
1> sp_attach_db @dbname = 'MyDB', @filename1 = N'C:\Documents and Settings\dtorg\My Documents\MyDB.mdf'
2>go

2) Create a FileDSN and select the 'MyDB' database
Administrative Tools->Data Sources (ODBC)
Select File DSN
Create a new file 'MyDB.dsn
Server: .\SQLExpress
Default database: 'MyDB'
Save the file :MyDB.dsn

3) Create a new report.
Select ODBC (RDO)
Select FindFileDNS: browse to MyDB.dsn
Select finish and you can then select your tables.

Alternate:
Select OLE DB (ADO)
Select SQL Native Client
Select server .\SQLEXPRESS
Select Integrated security
Select database 'MyDB'
Select finish and you can then select your tables.

I would rather use the following connect string to connect to the database. It eliminates the need to perform the sp_attach_db above.

Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Documents and Settings\dtorg\My Documents\MyDB.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True
