OOS Errors are minimal if you follow some basic rules. These can be found discussed on the Multiplayer bug threads, probably more on the ones that are just a little out of date for v37 than the current one, but it still mostly applies. Review those threads and see if it helps.
I'm sure you already told me that TBrd, but I forgot, where is this info? Is it only on that thread about OOSs someone asked long ago? I follow that thread BTW, but I haven't checked it in ages.
You're right, I'm Brazilian, and as such I speak Portuguese. The word "Infelizmente" which means unfortunately was typed wrong, which generated the inability to be translated automatically. I will edit the post above so that it can be understood.
I want to play online, emulating the LAN type connection is usually the easiest way to do this.
Greetings from Brazil too! As you may see on my Avatar info, I'm also from Brazil.

From what I understand, that's called Pitboss and I have no idea how to set it up so that it runs without error.
Emulating LAN connection is the same as playing in LAN or Direct IP (through an ip inside your LAN). I've always used Hamachi to do that, for at least 10 years already. Pitboss is a mode where one machine hosts the game and doesn't play it, and players join this game to make their turns. Turns have a preset time for them, usually a day, so players have to join once a day to make their turns. The mode is interesting, and is a faster approach to a crowded MP then PBEM, and more reliable then a normal MP. It's a shame C2C still doesn't work in Pitboss.

If you wish me to answer you in portuguese, just tell me and I'll do it. For now though let's keep it in english: TBrds answer to you is what you seek. To play in LAN you should use the Direct IP option because CIV comes from a time when LAN lobbys were full of bugs. Warcraft III had the same issues, and Age of Empires II too. Sometimes the lobby doesn't account for people connected to you, but a Direct IP usually works when the LAN lobby doesn't. Especially when emulating LAN through softwares like Hamachi.
In the case of Hamachi (and I believe all others do exactly like this), it creates a connection which simulates a LAN, and as such gives each member an IP code, which is usually called IPv4 (there's also an IPv6 which is useless here). On these softwares you must create a channel in which both you and any other player wanting to play through the internet must join (in Hamachi the maximum number of people in a channel is 5, unless you start to pay Hamachi to get more resources from the software).
After you and any others are in the same channel on your emulated LAN software, the one who creates the game has to share his IPv4 with the others so they can go to CIV -> Multiplayer -> Direct IP and type his IPv4. If everything is set correctly, all will join the game and everything is working.
But be cautious! You must get the host's IPv4 on the emulated LAN! If you use the Command Prompt and type 'ipconfig' you'll get all IPs for the computer, and there are usually more then one IPv4. You must get the one associated with your emulated LAN. In hamachi you can right click on the host's name in the channel and select 'copy IPv4'.
To end this, many times this approach will result in errors. The software may be in different versions on each machine, or it may be experiencing bugs that only a reinstall can resolve. Sometimes Firewalls can block it too. Opening the software as Administrator may make a difference as well. But don't worry, solving all these usually makes it work. It's reliable to an extent, but many small things make it not work. I hope this helps!
