i have the same problem. I downloaded several videos from R18 before they shut down (the filenames extensions however are .wsdcf and can only be played via the R18 software which is now not working). I tried using this javit tool and the instructions provided but KODI can't find the files even when I had a successful cataloging. i feel like there wasn't enough clear info or disclaimer info in the instructions to say that if you downloaded the files already before R18 shut down, then you can't use this tool anymore to bypass the DRM of those files.
