Hello i'm back,
and whenever I run Soldat it comes with the error about DirectX not being installed and to turn off Anistalising er whatever. Anistalising is off and I have DirectX9.0c and Soldat does not work.

Oh and by the way, I got 9.0c from Call of Duty 2 and I tried reinstalling it, and of course it doesn't work.

Whenever I have this problem, all I do is restart my computer, and it's gone.

I imagine your running a fairly new system (windows Xp and all that fancy crap, so what I'd suggest is you search the net for your Video Card manufacturer, and download the updated drivers for it.
Some of the websites you may find useful

www.ati.com/ - ATI Radeon Cards/ATI branded Video Cards
www.nvidia.com/page/home.html - Nvidia Cards (I don't know anything about these cards)
http://www.gigabyte.com.tw/ - Gigabyte Technoligies (also I don't no [CENSORED] about these cards)

Those are the three main Video Card Manufacturers. (bad spelling...)

If this doesn't work, try re-installing Soldat. If that doesn't work either, try buyin a new video card, or try playin it on a different computer (if theres more than one in the house)
Good Luck.
