Plutonium

So I had a fresh install of MW3 dedicated server tool from steam, followed all the steps, Opened the launcher, logged in, clicked on play, and it froze and closed.
I made a copy of my TeknoMW3 folder(that works absolutely fine) and put plutonium.exe followed the steps again, and the same error. It just closes, no errors or pop-ups.
Any one with the same errors or someone who knows a fix?
Thanks.
