When you start cmd, you get
C:\Users\Panda&Kitty
All you have to do is change directory using this
C:\Users\Panda&Kitty cd c:\jav-it
and you should now have
c:\jav-it
It looks like you you didn't type a space before typing the cd
Once you are in the correct path, you can type the script
c:\jav-it\jav-it.exe catalog -d <your_video_path>
YOU must have a space between -d and your video library location
From your message you didn't have a space
Hope this helps
