sounds like the firewall may be the problem. its allowing dhcp but blocking udp or something along them lines. open your firewall fully or set it to learning ode while you install the games. see if that fixes it... quick test would be to disable the fire wall to see if thats the issue. it could also be your router not forwarding the ports properly. especially if you have multiple pc's connected to... sorry i cant be more help... no sleep for 2 days...
