Hi all,im new here and i launch my multiplayer with IW4launch and i downloaded all that i need but it works for 30 seconds and than it just opens a error and my screen becomes black,please help me!Do you guys maybe know for a fix?

Press alt+enter in menu and wait till the error comes up. You should be able to read it, as alt+enter will run the game in windowed mode.

I fixed it,the problem was that i only downloaded iw23 cuz i saw that i have iw22 and later when i downloaded iw22 too and i replaced it it worked
