Warzone: Problem with Multiplayer

[Bruta]

So, me and and my friend play the old version of warzone, which is version 1.10
We played the game on multiplayer through two computers, connected to each other through a ethernet cord.
We played this way perfectly fine for a while, until recently.

At this point in time , we have got on warzone, connected through the internet to play two player with each other.
We can host and join a game just fine, but when the person hosting the game clicks "OK" the start the game, one of the computers has a problem, while the other computer works fine.

I get this message:

Warzone.exe has encountered a problem and needs to close

Can anyone out there help me with this problem, I would really appreciate it.

Did you try reinstalling, or crazy idea, the current version?
