Invalid Packet kick and ban

As of today I cannot play RO II. I keep getting session bands for Invalid Packet.

I looked it up and it said it was the firewall not working with the Punkbuster files.

But I do NOT HAVE A FIRE WALL and it happens even when I am running no anti-malware.

The internet connection seems normal, I restarted my router.

Any thoughts?
