ADE no longer working

I recently got a Nook Glowlight 3, so I started using ADE to transfer books borrowed from OverDrive. However, within the last week or so, ADE began acting up. At first, when I would open it, none of my files would show up. I did some research, both in Adobe forums and elsewhere, and did the “restore.old” renaming. That was a temporary fix. Then, it happened again...I uninstalled and reinstalled. It fixed again temporarily. When it kept happening, I uninstalled and reinstalled again, but this time it didn’t work. Finally, after leaving it alone a couple days, I opened it up again as I had new files and wanted to see if something had happened. Now, files displayed, but I got an error message that the files couldn’t be transferred. I saw a fix for that (deauthorizing and reauthorizing the device), so I tried to start the process. However, sometimes the program would freeze, leading to the need to force close through task manager, or just force close automatically upon trying to initiate the deauthorization. How do I fix this?
