Not able to DeDRM an epub

[irisvoo]

Hi everyone,

I am trying to DeDRM my ebook on Windows 10 but it just won't work, not in the latest versions of Calibre &DeDRM and also not in the 4.23 and 6.8.1 versions (mentioned in #1692 ). I purchased the book via a website that worked together with my Kobo Glo HD so when I logged into my Kobo it synchronizes my purchased books automatically. However, when I want to read it on another device, the website says I need to download it, it becomes an .ascm format, which i can open in ADE, saving it as .epub but then I can still not transfer it to a new device which is how I found out about this method.

Here is my log:

Hopefully someone technical can help me out!
