Need help with multiplayer

[teachingking]

Hello,

I am trying to set up a multiplayer with a friend over the internet. We have tried both Standard and Pitt Boss options. When we launch the game for the first time, everything works fine, but after I save (tried both Steam Cloud and Local) and load the game, he receives a "lost connection to host" message and the game re-starts without him.

My steps are:

Multiplayer>Standard or Pitt Boss>Internet>Host Game>Private Game
I invite my friend, and once he joins we start
After a turn, I save to a Local Drive (have also tried steam cloud) and close the game
Multiplayer>Standard or Pitt Boss>Internet>Load Game
I Invite my friend, and once he joins we start
It takes a while to load, and when it does, he is not in the game
He receives a 'lost connection to host' message


Any help would be much appreciated.

Thanks
