I found two ebooks in PDF format on a backup drive and want to access them again. They gave an error message saying they need to be opened by Adobe Digital Editions. However, when I used my current version, 2.0, to try to open the files they both gave the same error and failed.

Clik here to view.
What steps do I need to take to view old ebooks that were downloaded by older versions of the product??
Many thanks in advance.
