(adsbygoogle = window.adsbygoogle || []).push({}); Well, it's kind of stupid and noob for me asking this question, but it's really weird and I can't find a workaround.
So I've already created like 4 or 5 1.14 patches and I've never faced a single issue. However, I formatted my PC to Windows 10 one week ago and decided to create another MW2 patch just for fun and I'm stuck in a permanent black screen no matter what I do, always freezes entering the multiplayer menu.

Clean patch -> Works perfectly
Clean patch with just the multiplayer background color changed to blue, or the unknown CMD removed -> Black screen.

I just can't understand why, the patch region is perfectly correct (BLES00687) and no matter what I edit... Won't work.

If someone can link me any good or working .ff editor I'll appreciate it anyways. I'm facing a ton of problems. Help?

Re install the game it should fix your problem
