If you want to use a new Adobe ID to download eBooks in legacy versions of the OverDrive app (any version prior to 3.0), you'll first need to deauthorize the app (clear the Adobe ID you're currently using).
Note: Deauthorizing the OverDrive app disables all eBooks you currently have downloaded in the app. These titles are still tied to the original Adobe ID you downloaded them with.
