Not Responding When Downloading eBook

[#1]

My local library allows you to download books into ADE. When I select "download epub book" it opens ADE and the popup window shows that it has loaded completely but then stalls and ADE stops responding and the popup window stays up. I have tried redownloading the app, reauthorizing and even the registry editor trick but the app continues to stop responding the minute I try to download a book.
