The Adobe Digital Editions (ADE) message "Unable to download" often results when you have been trying to use the ebook on two different computers, where the second computer's ADE software is not authorized under the same Adobe ID that the first computer's ADE software was authorized under, or the second computer's software has not been authorized at all. Check both computer' authorizations by opening ADE on both, clicking "Help" on the menu bar and then "Authorization Information" to see if the two email addresses are identical. If they are different, click "Erase Authorization" on the second one, then "Authorize Computer" with that first Adobe ID. See if that helps.
If you have saved the .acsm file for a title to a memory stick and then tried to open it on another computer that could also cause problems.
Another possibility is that the ebook's loan period has expired.
