Problem with Update

Hello everyone

i had a version of the game( 1.4.382 )and it was working for me fine
i updated my game to the 1.5.387 version so that i can use hacks and cheats
but fortunately Multiplayer game doesn't work with me like it was working with the 1.4.382 version

the things i wanna knew is that :

1: Does the 1.5.387 version Multiplayer works for free? or i have to buy a serial so that i could update the game to the 1.5.387 version and play Multiplayer?

2: Is there any updates after the 1.4.382 version? i saw somebody talking about a 1.4.387 version? if so please provide me for links

3: If there isn't any of what i mentioned
please provide me some links for a nametag hacks to the 1.4.382 version
cause i searched for any of them but in vain

Altermw3 version is 1.4.382 so if u wonna play via altermw3 server ul need v1.4.382 :P

Mine is keep saying unbale to connect to server please contact callofuty.com/mw3

You guys should stop being newby just like that AIW Hacks thread in the same section here, some nobs even manage to not see it and say they searched for working hacks. How the hell did u get the idea u would need to updating your game version "manualy" ? Itsfreakin auto-updates ? LIKE WTFH?
Next time use your eye's before randomly doing weird stuff that doesnt make sense @ all.....
