'DirectX' Problem
If you don't have DirectX 8.1 or later installed, then you should install it now and see if that fixes the problem. You can get the latest version of DirectX from the Microsoft web site at www.microsoft.com/directx
If you already have DirectX 8.1 or later installed, then try these fixes:
Possible Fix #1
If you have Windows XP and you recently installed some Microsoft Security Updates, we are getting some reports that one of those updates is having unintended side effects, one of which is that it causes the game to erroneously report this error. The security update is:
Q811493: Security Update (Windows XP)
If this applies to you, then try uninstalling the update, then try the game again.
Possible Fix #2
This newly available patch is available here and fixes this problem for many people (although some people unfortunately continue to experience this problem even after applying the patch) Download the patch and install it to see if it fixes the problem.
Possible Fix #3
If the above fixes didn't work for you then try this:
1. On the game's main menu, click on "Options"
2. Click on "Performance"
3. Click on "Manually Adjust Settings..."
4. Find "Allow Projectors" and turn it off
Now try the game again. The only thing you'll be missing as a result of turning of projectors is that you won't see grafitti on the walls of some buildings and you won't see lines painted on the streets.
