@shannara76 Please manually reinstall DirectX 9, as described here:

You don't need to uninstall anything; just run the installer over the top and restart your computer.
If that doesn't help, please reinstall .NET Framework 3.5. Hit Windows key-R, enter "appwiz.cpl" without quotes, click "Turn Windows features on or off," and you'll see .NET 3.5 near the top of the list of features. Click the filled-in box to uninstall, and restart your computer. Then repeat the process, except this time, click the now-empty box to reinstall, and restart again.
If that doesn't help either, please uninstall and reinstall VC++ 2005 x86. Hit Windows key-i, select Apps, scroll down to the Microsoft Visual C++ Redistributables, click on the 2005 version, and select Uninstall. You can get a fresh copy directly from Microsoft:

You only need the x86 version, not the other two. Restart your computer after installing and before trying to play.
If you get the same error, or a different one, please post a screenshot. Please also post a new dxdiag either way.
