ADE has stopped working

[barbarap87060898]

Now I'm getting this message whenever I try to download a book from the library!  Using Windows 10 and a Kobo. 

I have absolutely no idea how to go forward - no idea where to even start.  Basically I'm hooped.

I have uninstalled and reinstalled ADE at least three times.  I restarted my computer several times, I've even yelled at it and made severe unpleasant threats, but nothing has helped.

Anyone - any suggestions, please!

What try you and what happens exactly?

[barbarap87060898]

Just what I said - as soon as I try to download the ebook to my kobo, ADE stops working.

Do used which version of Digital Edition?

[barbarap87060898]

I have used the current version 4.5.1  and 3.0 both with the same message - ADE has stopped working.

Have you both version installed to the same time?
