Brianasht,
I'm assuming you mean "drivers" for your PC?
It's very likely, however, these depend on the manufacturers of the equipment:-
As an example, my PC has a Gigabyte Motherboard, nVidia Graphics and Hercules sound card, running Windows XP (Service pack 2).
I have to check with Gigiabyte, nVidia and Hercules to make sure that these drivers are up-to-date.
Then I need to use Microsoft to make sure that Windows is up-to-date, then "just" check that there's nothing new for DX!
Quick suggestion - try this:-
find the file "trainzoptions.txt"
now use notepad and edit the file to disable the intro video - the format's is in the manual.
This often gets past the can't start problem...
