i have bought a laptop with windows 7 already on it. now when i try to play counter strike using steam it works fine, but when i try to play condition zero or day of defeat i get fatalerror NET_Sendpacket ERROR WPAEACCESS! when i try to play those games on my old windows xp pc it works perfectly... i thought that the firewall or antivirus blocked them but i have disabled the firewall and uninstalled the antivirus and it still says the same thing. i am using a wireless connection, but tried a wired one and i still got the same problem i tried lots of solutions i found online but none of them worked for me so i really need help. this is a big problem and i think that same thing will happen to steam games i want to buy in future... games like BF2:Complete Collection... Help me fix this please!!
