Hi again,
No worries, I'm happy to help. So the two commands you would want to run is this:
cd D:\Compressed
jav-it.exe download -c r18.com_cookies.txt -o D:\Compressed\JAV -i kwbd00105
The first command changes to your install location, and the second command runs Jav-It. Note that for your output directory you specified `D:\Compressed\JAV`, so make sure that the `JAV` folder really does exist under `Compressed` before you run this. Give this a try and let me know! I'm excited to hear if it works for you!
