Where to find ADE 3.0 for old Nook e-reader

[41BF]

My old Nook e-reader apparently will not work with ADE 4.5, which I downloaded yesterday. Many hours of trying to no effect, but I found a response in the forum that indicates I should go back to ADE 3.0. Wouldn't you know, I uninstalled it! Have been searching the Adobe site for ADE 3.0 with no luck. So where can I find ADE 3.0 to download?

There's a link to downloading ADE 3.0 on the same page as downloading ADE 4.5. Keep scrolling down to find it.  Live chat about ADE told me about the link. And it worked.  I had to re-associate 3.0 as the program to use with acsm files (maybe not correct acronym) on my computer.  Now Overdrive works to download library books, and Nook is associated with the right things on my computer.
