Digital Editions issue on several devices simultaneously.

What has happened if Digital Editions crashes on Windows, Mac and iOS same day?

It freezes on Windows and cannot see the books/libraries.

Crashes when opening in Mac OS.

Iphone app when clicked doesn´t open the app, it just blinks and close.

Version is 4.5.12.112. Restarted router, restarted devices, re-installed app without any solution. Also re-authorized devicets etc. It has worked perfectly fine until yesterday and today but now all device versions crash.
