I used to play AlterIWnet , and i just found out that the game has opened again as FourDeltaOne.
(I know its been some months since its open again ,but i didnt notice it /facepalm )
So , i have deleted the MW2 Files and everything.
What do i need to install it again ? Since they only provide something like a Client Updater or something.
If anyone knows how to install it e.t.c reply please.
