Plutonium fails to authenticate

[Hoggy]

When I press play on a solo game of zombies the countdown will finish and then the game will go black and once it comes back it will say that plutonium has failed to authenticate. Can anyone help fix this. I've restarted my game countless times and nothing ha s worked.

@xdZombieSlayer You need to update pluto, it now uses the pluto launcher. https://forum.plutonium.pw/topic/2819/how-to-install-update-plutonium-t6
