hi..im so sorry maybe this topic is very basic and familiar for u all, but i already seen the Philony topic here viewtopic.php?t=2097&p=5886 and i got the same problem...
i already installed modern warfare 2 and i do not add any mod or something, just ordinary game for me to play single player..
but i tried to play multiplayer and follow instruction at this page and i got crash and the dialog that say "Preview_MP_Contact" apperared..
i already read jeremych solution "verify game cache" and i dont know how to do it..
i googling it and find that verifying the game via steam..
but when i open steam, i cant find any games in my steam library...
i tried to put manually but the only option appeared is "add non-steam games" and i ca put mw2 on steam library..
the question is, when i right clicked mw2.exe and see its properties i cant find "verify game cache"
so any solution to my problem so i can play it online?
oh ya one more, i already downloaded iw_23.iwd (i find solution from this forum but i forgot who posted it ) and i already copy it to my main directory but my problem still occured..
i highly appreciate any help here..thanks and im so sorry for my english...
