Well I never had this problem before....
Just changed video cards from ATI to Nvidia.I uninstalled the ATI drivers etc before fitting the Nvidia card with latest drivers but TvT now crashes when you click to start the mission.
I did a clean install of TvT but still no luck.
It ran before with the very same Nvidia card.Weird.
I have all of those 'missing' files in the TvT folder and Windows/System folder too.
This isn't a game problem I am sure,it's something to do with the swap over of video cards.
I am going to try a few things first.Stand by....
