Not sure if you've been able to make it work yet, but what i could find from korean forums is just to install a plugin for chrome so you can right-click. I think it's called "allow right click" or something similar. Check to see if that works. I don't have likey myself so i can't try it unfortunately.
I usedchrome plugins before like video downloader plus and image downloader it worked but was slow. I just use IDM (Internet download manager) I can rip wall content but can't rip DM PPVs.
