I found an article about this ussue on the steam support pages, but none of the available fixes actually fix it for me...oh and just today I realised the problem isnt restricted to just TF2, no steam games will run, they all just pop up with that error. Ive heard around the forums that whatever is happening might have been caused by the latest steam client update, but so far nothing I do seems to fix it. In any event, I have been able to play steam games fine on my laptop before, so its obviously something that has happened since the last time I played a steam game, which I dont know when that was...
