I don't understand what's happenning. Since this week, I couldn't play tf2 anymore. Everytime I launch tf2, it said that steam isn't connected so I couldn't join any server.
But in fact steam is connected to internet, I don't understand what is the problem.

, its right in your program files/Steam folder, not in the TF2 folder. When you start up steam after that it should say 'updating' as it redownloads the file, after that it will hopefully start, it fixed a similar error for me
