When I launch COD4 on version COD4x 21.1, it seems to work normally, but it crashes every time I try to start a game. I don’t know why it does this. Games launch fine when I use version 1.8.

That’s your problem. You are using steam version 1.8. You need to downgrade to 1.7 and the install cod4x.

I am on disc version so can’t help you with it

Anyone on steam version who can help?

Yeah, you just need to find a 1.7 iw3mp.exe and replace it. That’s it really. Than go ahead and install the cod4x update on top of it.
