error when attempting to download certain files

[rakuko1]

recently downloaded the new version to see if it helped with a separate error i was receiving, started noticing this kind of error was showing up for most files I downloaded:

2024-01-31 16:11:09.673 -08:00 [ERR] Exception caught: Could not find file '[filepath]\0hf2t147dv4an99q2w9xl_source.mp4'.

presumably just a minor check error due to config renaming the files after download, but figured I'd report. the files are fine, it just pops up for every individual file.

it's still happening on occasion, this time for some purchased videos. does download the rest of the videos but not certain ones oddly.

ok, updated to newest version, error has changed to this:

2024-02-19 01:02:30.137 -08:00 [ERR] Exception caught: Cannot start process because a file name has not been provided.

I think that's throwing an error when trying to locate ffmpeg. Double check your configuration and make sure that you have the correct path set for ffmpeg.exe (remember that the path needs to use forward slashes, not backslashes). I think you might not have that set currently, and that is used specifically when dealing with videos that have DRM, which would explain why it's only happening on some content.

the second error might have been because of the ffmpeg.exe path because of shifting from auth.json to config.json. that being said, for those same files i get the original error after adjusting the path:

2024-02-22 09:40:55.766 -08:00 [ERR] Exception caught: Could not find file '[folder]\Messages\Free\Videos\0hhizz9fdwgfzkloy40x7_source.mp4'.

if it's a DRM issue, it is a selective DRM issue because i am able to download some DRM videos.
