Recent Windows update crashing ADE

I have three computers, two with W7 and one with W10.  All three worked fine with ADE - well, never totally fine, since there are periodic reauthorizations are needed with ADE, etc.  But since the most recent Windows updates, about a week or so ago, ADE has stopped working on all three machines.  The program starts but there is only a blank screen, "My Library" is empty, and I am totally unable to download anything.  The program does recognize the plugged in Kobo reader, but when I double click on the device, the program crashes and exits.

I have reinstalled ADE, and there is no difference after the reinstallation.  I can't imagine that I am the only one having this problem, but the situation certainly makes me very grumpy.

Incidentally, when we are locked into ADE because on-line books cannot be accessed without it, I think there is an obligation on the company to provide some support directly, and not just open up a forum.
