I think you must have Sony's eBL "associated" with the ePub filetype. Probably Sony did this automatically for you when eBL was installed. What you need is for the download to be handled by Desktop Adobe Digital Editions. The download is actually an .acsm file, which ADE uses to get the actual ePub for you. The web browser is seeing the .acsm file and is opening Sony eBL to process it - this isn't BoB's fault although they can probably tell you how to fix the problem.
