DeDRM returns blank PDF: Syntax Error: Couldn't find the 'EBX_HANDLER' security handler #250

Question / bug report

I've bought an ebook through Google Play and I'm trying to read it on my kindle. I've downloaded the book as an .acsm file and opened it with Adobe Digital Editions 4.5. Once I open it, I can read it on ADE, but when I locate the file I can only find a blank PDF. I assumed this was due to DRM, so I'm attempting to use deDRM to remove the DRM. I've installed the plugin and loaded my Adobe ID key, but when I import the PDF file into the library it stays blank.

Which version of Calibre are you running?

6.11.0

Which version of the DeDRM plugin are you running?

v10.0.3

If applicable, which version of the Kindle software are you running?

No response

Delete the Adobe key from DeDRM's customization. Re-add the book to calibre letting DeDRM automatically retrieve the key on its own.

caeochoa commented 1 year ago

Thank you! I did that but I'm still having the same problem unfortunately :( -- the pdf appears blank on my calibre library. The error seems different though, so that's promising. Do you know what I can do now?

ElleKayEm commented 1 year ago

ADE used to download the pdf (and where you can read it) is on the same machine and user as calibre with DeDRM? Was ADE authorized with an Adobe ID?

harenber commented 1 year ago

See the same and can confirm that ADE was authorized (tried both Linux and Mac). An older PDF downloaded by ADE still works, so it seems like something has changed in the PDF format.
