It's just an error (******** error of your ******** *****) when I start IW5M : "code_pre_gfx_mp".

Anybody to help me please ? :?

Delete caches.xml in your IW5M folder and run LaunchIW5M.exe. Same thing happened to me.

I already did it, but it doesn't help. :/

are you sure you using IW5M? bcuz when you delete caches.xml and run "launchiw5m.exe" the error is solved.

It won't help if you're not running the english version of the game.

If you're running the english version of the game, then deleting caches.xml before launching the game will fix that problem.
