Microsoft Data Link (.udl) problem

[hyarmion]

I am attempting to connect to an Access 2010 database using a Microsoft Data Link (a .udl file). I have password protected (encrypted) the Access 2010 databse.
Within the Data Link, I specify:

Provider: "Microsoft Access 12.0 Access Database Engine OLE DB Provider"

Connection: Data Source: <path><database name>.accdb

The password is entered under the "Use a specific user name and password section."

When I click the Test Connection button I get this message:
"Test connection failed because of an error initializing provider. Cannot start your application. The workgroup information file is missing or opened exclusively by another user."

Note: The Data Link worked fine before I password protected the database.

Anyone seen this before?

Correction to the above post, the database I am attempting to connect to is an Access 2007 one, not Access 2010, but that was just a typo, the problem remains.
