I have deleted %localappdata%/Plutonium folder and launched plutonium.exe. I am opening the game with plutonium.exe. I have deleted plutonium.exe and downloaded it again. Each time I try to open zombies it comes up with a cmd and then says 'Could not authenticate to Plutonium: snowroller uninitialized'. Switching to LAN and launching the game does work but theres obviously no multiplayer.
@alonsopuente i also have this problem to and it also somtimes says for me that a connection
