third how i can install updates when i enterd in store it many links and my coneection is not speed enough only 1 miga so what is the important updates to provide me all maps open

 

last i want to thank this website for multiplayer for this game

Your first problem is related with your third problem. You can't play on all maps because you didn't get them all yet.

As for your second problem, friends system is not implemented on IW5M

thank u very much i will download all links
