I've just started using the tf2 offline version as we will be soon supporting it at our lan events.
When i try and launch the game i get the following error - "Error reading application id. Please either write to steam_appid.txt or use the launcher!"
I am using a bat file with the following command: start hl2.exe -steam -game tf -appid 440 -console -novid
I am running version 22.214.171.124 with the fix (Am in the process of downloading the rest of the updates)
If anyone can help me i would appreciate it.
Many thanks in advance
