I didn't think updating DirectX would work but anyway is your window registry that didn't Install properly or got remove when you uninstall a software that can leave your registry with a obsolete files It is usually safe to replace your dll files with another one from another windows
so try downloading the dll file below and check it if that solves your problem
http://www.dll4free.com/msvcr71.dll.html
you would have to open the zip-file you have downloaded and Extract the dll to Windows System Folder C:\Windows\System32
if you're unsure what to do i would suggest that you take your computer to a computer shop or someone who know how to fix it for you as this is a missing registry in your window as this got nothing to do with the game.
hope it help.
also on aside note the game is call Men
of War Assault Squad not "men
at war assault squad"
