I got 2 books from them last night. One was free because they were nice enough to send me a coupon!

I only got an email for one of them to download to ADE. The other one I was able to download from the site but it took me awhile to figure out how to do it as there was no download button for it.
Questions:
1. The one I downloaded from the e-mail I ended up with 8 copies on ADE. Totally my fault but how do I get rid of them? edit- Never mind this one. I see how to do it now.
2. I really wanted to download them to my PC. Is the reason I couldn't because ADE was open and is there a way to do that now? edit- I figured this out too but it doesn't download as an epub.
3. If I would have had the Sony elibrary open instead, would it have downloaded to that? edit- I am thinking the answer to this is No.
