Issues downloading DRM

I'm having issues downloading videos using DRM. I used to be able to bypass this issue using OF-DRM but i guess an update prevented that program from working i now receive the following errors:

Exception caught: Object reference not set to an instance of an object.

Try following https://sim0n00ps.github.io/OF-DL/docs/config/cdm and see if that helps.

i actually did generate my own widevide keys so i’m not sure why this is happening. i’m using windows 10, 32 bit so i’m using an older version of ffmpeg. could that be the reason?
