Using Offline Mode
Please follow the instructions below to configure Offline Mode on your machine:
1. Start Steam online - make sure the Remember my password box on the login window is checked
to. Verify that all game files are completely updated - you can see the update status for a game under the My Games tab (when the game shows as 100% - Ready it is ready to be played in Offline Mode)
3. Launch the game you would like to play offline to verify that there are no further updates to download - shut down the game and return to Steam once you have confirmed that the game can be played
4. Go to Settings to ensure the Do not store account information on this computer option is not selected
5. From the main Steam window, go to File and select Go Offline
6. Click OK to restart Steam in Offline Mode
7. (Added by me) Launch the game again and select offline mode when the game asks. The first time I didn't, I just shut down my laptop and move it, and it wouldn't work. So Be sure to launch it again right away in offline mode.
