ask steam support?
Srsly tho, First right click on tf2 in the steam browser and select properties > go to the local files tab > and select verify game files > try launching tf2 now.
If still not cooperating; re-download the steam installer form http://www.steampowered.com > run it and select repair > but not not uninstall! after it runs, re-login and see if that does it for you by relaunching tf2.
