The only reason they're updated is because we manually opened a ticket with our host, NFO, to repair / replace all files on each install. If no ticket was opened the servers would still be running the outdated version. When I went thought the MSI nearly all servers running outdated versions of PunkBuster were from the same host, the one I'm using, which makes me believe something is up with our host.
The servers were just restarted this AM. =( I'll post again to the Even Balance ticket, maybe they'll feel generous and respond.
