Problem installing Digital Editions

Hi

I just tried to download and install Digital Editions on my MacBook Pro, but get this message that ADE 4.5 "wants to access key "Digital Editions" in your keytchain. To allow this, enter the "login" keychain password."

When I enter my Adobe ID password it shakes no. I even tried my admin password, no go.

What password do they want?

What can I do?
