So, alright. I've done extensive research on this problem. What happens is I start steam, go to launch TF2. It gives me the "Launching TF2" screen, and then it disappears. Nothing starts. HL2.exe doesn't even start. Now, here's what I've done (according to my research): Reinstalled video card drivers. Verified game data Exception listed it in ALL of my Anti-Viral and Anti-Spyware programs (AVG, Ad-Aware, Spybot S&D) Copied blinkw32.dll into the TF2 folder (from it's bin folder) Moved Steam and all its installs to a new drive Nothing has worked thus far. Any ideas?
