Boas,
podes sempre sacar o offline steam para conseguir contornar esse problema, nao deixa de ser um "crack" mas em principio funciona lindamente.
ja agora da uma vista de olhos aqui:

"Two Scenarios:
1. My friend has no Internet connection, how can he set things up so he can play offline?
2. I want to be able to play at a LAN party and they won't have an internet connection there, how can we all play offline?
Answer:
There are several ways to do this that will work for players without Internet access as well as for LAN Parties where there won't be internet access.
Note:
You have to be online somewhere at least once to perform all of the following steps.
The first step here is to perform the latest update and capture it. This is very important to make sure you get the latest content and bug fixes. Everyone that will be participating at the LAN event must have the latest update!
Easiest way
Bring the computer that will be playing offline to an available internet connection at a friend's house, school or perhaps business. Log into the account and do all the updates, make sure it all works.
Then "exit" (do not log out!) from Steam, go to the Steam folder and make a copy of the clientregistry.blob file (just in case). Write-protect the copy (mark it Read/Only).
Physically unplug the computer from the internet, start up Steam and let it fall back into offline mode. Make sure the computer will play both Listenserver (LAN), client and the single player ok, then exit from Steam again.
WIN98
If this is a WIN98 computer, it will act like it's stuck updating and not logging in, JUST WAIT! It will take about 90 seconds for it to finally figure out that there isn't an active internet connection then it will prompt you to retry or go into offline mode.
The computer is now ready to play offline at home unless he accidentally logs out ...
If he does this he won't be able to play unless he verifies online again >> or << exits from Steam, then copies the copy of the clientregistry.blob file back which will restore his offline play.
NOTE: MAKE SURE THE ACTIVE ClientRegistry.blob FILE IS NOT WRITE PROTECTED!
It certainly wouldn't hurt to burn a CD of the working offline installation for him."
