Plutonium

When launching the zombies server bat file it loads and then this error appears on every heartbeat attempt:

Any fix for this? Haven't seen anything else about this on the forums. I've changed server key, I have correctly server ported because the server was working before the most recent update. I had a few friends experiencing this same error when launching the plutonium launcher but they fixed this by launching as admin. When attempting to launch the bat file as admin it opens and then quickly closes immediately after.

Amusedd have you figured out a solution to the Z++ problem

so i installed the maps and theyre working but the zombie's health stays at round 1 health, got to round 15 and they were still getting one knifed and no there wasn't a instakill.
