Ascm file not opening in ADE, error message

marp68 · 03-20-2025, 01:11 PM

Borrowed and donwloaded/opened the ascm file in ADE, but got the message: Error getting License. License Server Communication Problem: E_ADEPT_DOCUMENT_TYPE_UNKNOWN.

The strange thing is that it worked fine with another book I borrowed a few minutes before the second book.

So does anyone know a solution? I googled and find examples of solution of which on one was successfull. I deauhtorized/auhtorized the computer (Windows), I erased temp files and everything else, deleted the ascm file, reinstalled the ADE, donwloaded the file first before opening it in ADE, etc. Nothing worked.

I also downloaded the ascm file to my Android phone and open it in the ADE there, but with the same error message. So does this mean that the error might be in the actual ascm file?

These types of problems seem to be getting more frequent. Yes, it's possible the ACSM file is invalid, so you could try downloading it again, but a common solution these days is to give up on ADE and switch to the ACSM input plugin for Calibre, instead. I had to do that myself last year when ADE started giving me a cryptic error message, too.
