I'm on Mavericks, and I had Adobe Digital Editions 2.0. I bought a .epub from the Kobo store (UK), downloaded the URLLink.acsm file, double-clicked it. ADE opened, downloaded the book - and quit. The application closed, there was a pop-up asking if I'd like to report to Apple that the program quit unexpectedly:
Adobe Digital Editions quit unexpectedly.
Click Reopen to open the application again. Click Report to see more detailed information and send a report to Apple.
Ignore / Report... / Reopen
I tried reopening by double-clicking the application icon in the Applications folder, and it opened and then immediately closed. Same error message. Same when I click Reopen on the error pop-up.
I then looked to see if there was a newer version of ADE. There was; 3.0. I deleted the old 2.0 version and then installed 3.0.
I double-clicked the new icon, but it opened and then immediately closed itself again. I tried downloading a new book (one of the ADE sample books), and double-clicked the new URLLink.acsm, but the application opened and then immediately closed; it didn't even get as far as downloading the book.
I am mystified. What do I do?
