Thanks for your message.

If I'm understanding this correctly you have opened the ACSM file in Adobe, and when you now open it again in Calibre with my plugin, it works?

The best case for non-working ACSM files is to create a debug log in Calibre (Preferences -> Restart in debug mode), then try to open the ACSM, and then send me the resulting debug log file. But now that Calibre successfully opens the ACSM file, that's no longer possible. Looks like only the initial fulfillment of the book didn't work through my plugin, but future fulfillments (which work a bit differently) do work.

I doubt there's much I can do about that now - if you encounter a book like that again, please do not try to download it through ADE, and instead create a debug log through the plugin and send that to me.

EDIT: Okay, I just wasted €3.99 and bought that book myself - that looks like it's a temporary issue on Thalia's server. I added the ACSM to calibre and it didn't work 1st try (the server responded with 403), but it did work the 2nd time and all I did was add some more debug logs. Then I tried it a couple more times and sometimes it worked and sometimes it didn't. I'm assuming Thalia just has some issues with their servers right now, and that your 2nd attempt with ADE just happened to work. Or maybe ADE has some code to automatically retry on error.
