mw3 crashing problem

Did you get this error after the map pack 2 patch? I've been googling and it seems an common problem, maybe Infinity Ward is working on a fix

I got this error after the update. The 1.9.xxx thing.

Well, wait a week or longer. Maybe Infinity Ward will fix it, you can also check their site for a topic about this problem

Alright. Thanks for the help

Might also try updating DirectX, google for a DirectX Update check, and re-validating your game files.

I always get this error when I play in windowed(no border) mode. Fullscreen has no problem. This is weird.

I dont know if this will fix your problem but it is worth a try

Step 1: Log out of steam and close the application comepletely (Task Manager after loggin out)
Step 2: Go to your steam folder in your program filee
Step 3: Search in the steam folder for a folder labeled "appcache"
Step 4: Delete the folder labeled as "appcache"
Step 5: Restart steam and log in the boot your game and see if the problem is solved

IDK if iut will fix this problem but I know it is working for the people wiht the new DLC getting the Invalid map file errors

Yea....that unfortunately didn't work.

Ok. It is working now. Thanks for the help guys I just have to run Mw3 full screen and that will fix the problem.
