I just bought the itch.io version and downloaded the file. There was no download.bat there. I downloaded the helpfile and found a download.bat. I added that to my extracted Jav-IT folder,
I added the extension "Get cookies.text" and then logged into my R18 account using the Brave browser.
I watched a couple of videos in my library to note the CID. I then exported the file from the Get cookies extension and placed it in the JAV-ID folder.
I ran the download.bat and typed R18. I then entered the CID code as I saw when I watched the file.
I got an error message stating: Fail - A valid cookie file is missing or does not exist.
What do I do to correct this. Thank you.
EDIT: I renamed the cookies file to cookies.txt and it started to download but then I got a message that stated "The provided video ID did not return any streams." It states "login required". I am already logged in.
EDIT 2: I needed the cookie from the actual page where the video is streaming from :)
