We need more information
I am going to use this thread, because it asks the same question I have.
I recently got set up with e-library account and overdrive.
I run an Imac with OS 10.13.3
I downloaded adobe ADE 4.5.6
I successfully borrowed two ebooks, and transfered them to the Kobo device.
Once those were read, I deleted them in ADE, and returned them in overdrive.
Now, when trying to get the next ebook onto the Kobo, I get stuck trying to get it into ADE.
I borrowed the ebook, downloaded the copy to my downloads file. When trying to drag the .ascm file into ADE, nothing happens. If I go through the file menu to manually select it from the same folder, it is not selectable.
I am stumped, and haven't found any troubleshooting for this issue. Seem like this is overly complicated, and when a program fails at its sole purpose, I get frustrated....
Thanks for any help....
