Can't download library books to my ADE, v. 3.0 from Mac OS X, with Yosemite download

[Guest]

i have a Mac OS X 10 w. Yosemite download.  am having trouble downloading library books to ADE, v. 3.0, which i would then like to transfer to my Simple touch Nook.  I noticed that the authorization is for a DRM but the books are ACSM.  should i change the computer authorization and if so, how do i do this?

The ACSM file is a link to the site you're borrowing the book from. The actual book (pdf/epub) should be located in the Documents folder.

Thank you. I did find a book that i had checked out from the library in the documents file. however, the book wants to open in iBooks. i want the book to go to my Simple Touch Nook and i thought that i could only do that through ADE, v. 3, which i have downloaded (several times). however i can’t get the library books to download or go to ADE anymore. I reauthorized the computer, using an Overdrive authorization, but i still can’t get books to download to ADE. i believe that before all this trouble, i had an ADE authorization. I was wondering if i should de-authorize the computer (but don’t know how to do that) and re-insert an ADE authorization. (but of course i don’t really know how to do that either). i have spent so much time one this matter that i can’t remember what i’ve done. Nook and Apple say that this is an ADE problem, and i have reviewed the discussions in the Forums, but so far i haven’t found anything exactly on point — or perhaps i just don’t recognize an answer that is staring me in the face.

on my previous message i forgot to ask: any ideas?

Just wanted you to know that i went back and tried again, was able to re-authorize the computer (and Nook) and, lo and hehold, it worked! So no need to respond any more. It was the authorization that was the issue.
