I've been searching around the interwebs for a solution, but with no luck.
Whenever I attempt to run VAC Chaos, it gives me the following error: "Unable to communicate with VAC Chaos module. Please allow network access and try again".
I thought the message was obvious, so I went to disable my firewall and I also disabled UAC. Yet still, I get this error. I also run both Steam and VAC Chaos as Admin.

Hope I can get some help
