Plutonium

I wanted to play the game on a car ride.
I tried just using the launcher, but it prompts me to log in.
I then tried launching it directly by command prompt using this: "plutonium-bootstrapper-win32.exe /app "C:\Users\morgo\AppData\Local\Plutonium\games\t6zm.exe" -lan"
But then it tells me it's unable to load binary into memory.

Is there an offline mode on the launcher that I'm missing?
Am I inputting the command wrong/using the wrong program? (morgo is my username btw)

Edit: Yes I put the command prompt into admin mode

TwirlTM i have. no luck.

Attempting to play Zombies with a friend.
Says UPnP disabled, despite having it enabled on my WiFi router, having my network set to private, and having Win Fire disabled.

Can't port forward because Xfinity likes to block all incoming connections when I do.
