please help!
Steam works, but it says I didn't shut down properly and would I like to start in safe mode.........well, it doesn't start up in safe or normal mode,...i just get the small black screen and the program doesn't respond. Any suggestions?
Would I have to re-install the game? would I lose my levels? (I'm between level 69 and 70!!!!! Eish!!)
Please help

Go to C:/Program Files/Steam/Steam Apps/common/call of duty modern warfare 2/players.....

And open the "config_mp.cfg" in NOTEPAD

Once its open in Notepad go to Edit->Find and type "fullscreen"

Immediately after the word fullscreen you will see a number in quotes like this : "1"

Change this number to a "0" and SAVE the file.

Start muliplayer and you will see that it starts in a window.... Go to your graphics options and under advanced make sure the "Screen Refresh Rate" is set to 60 (or what ever your monitor supports, mine was set to 56Hz which failed horribly so I reset to 60.)

Hope this helps.

with the above steps, go to task manager >> processes >> iw4mp.exe >> right-click >> affinity >> tick only: "CPU 0" and "CPU 1" >> task manager again >> tick "all CPU" >> switch back to iw4mp.exe and wait for it to load

It still won't work for me, can someone help me please? I did all the above except what heeeeey said because I didn't understand that.

When I start MW2 I get this screen I press yes, then I get this and I press yes again and finally I get to this screen where it does nothing and when I hover my mouse over it I can see its loading.

My specs are:
Windows 10 64-bit
Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz 2.30 GHz
NVIDIA GeForce 750m

Please help me

You should probably wait for like 10 20 minutes.
I wait that long to play other games like Gary's mod it eventually loads

I have found a way to get the multi-player working again, but this may not work for all people. So I will describe the symptoms that my game had and if you are having the same then this should work;

1 Single player is working ok

2 Multi-player does not work;
Application starts, shows the splash screen then the screen goes black and then nothing........... application hangs and you have to press ctrl, alt and del to start task manager and end iw4mp.exe that is no longer responding.

3 you start the application again and get the option for safe mode and go back up to 2.

4 you remove game content through steam and re-download or restore from backup and multi-player still does not work.

if this is sounding familiar then this is what I did to get the game working, which is possible the long way but here goes;

In steam, select "Backup game files" for Call of Duty: Modern Warfare 2 and multi-player, (select both titles in the backup list). Then select Delete local content for both single player and multi player.

Next, locate your steam common folder, eg; D:\Steam\steamapps\common\ there should be a folder called"call of duty modern warfare 2"

I deleted this folder, you may wish to move this folder to another location like your desktop.

Then restore modern warfare from the backup you made earlier and allow it to update and resync

lastly, start multi-player as normal ....... you may get a message "completing installation" .......... just retry and it should start up allowing you to set key bindings etc...


I am guessing that simply renaming the dir "players" to something else could also work and may be quicker but as my game is working ok i am unable to verify, however the single player profiles are also in the players dir so its worth keeping it in a safe place.

it worked for me with re-instaling it, if u wanna save u'r singleplayer saves just go to Steam/Steamapps/common/Call of duty Moderne Warfare 2 find the file players and save it to another file(the online stats are stored online) when u have re-instaled it u just replace the players list with the original.
that worked for me atleast =P

You don't have to reinstall the game I have tried 3 times it does not work. so my answer is step 1- Go online on steam
step 2- unplug your ethernet cable
step 3- do not exit steam
step 4- start the game either multiplayer or single player
step 5- plug in your ethernet cable to access online service
hope this helps
