Yikes hw, I seem to have been lucky with downloading straight into my Sony Reader for PC cos I've never had a drop of trouble .....
Oh yep, I know that Sony has ADE embedded, but I don't actually have to deal with the ADE for PC app, or any other ADE app. Phew ....

... that's why I like it and do it the way I do.
Maybe I haven't had any download glitches because of the sites I buy from ....
