Plutonium

So I just downloaded the 'piry' file from the official Plutonium page. I installed everything and everything seems to be good. I go ahead and launch BO2 Multiplayer as admin, and it opens a CMD windows which displays Steam callback dispatch. It also opens another windows with the game. When I hover over the start bar, I can see BO2 there, but when I go and press it, nothing happens and it brings me back to my desktop.
Any fixes?
Thanks
