Hello Olympic,
Welcome to the Forum.
Please attach the Dxdiag of your computer. It can be verified if your PC is compliant with the System Requirements of SSE.
How to obtain your DxDiag file:
1. From the desktop click: Start > Run (or windows key + r).
2. In the blank text field of the window that appears type “dxdiag†without the quotes. Press run or hit enter.
3. Another window should appear titled DirectX Diagnostic Tool. Near the bottom of the window click on “Save All Information…†A popup should appear with a progress bar, this may take a few minutes.
4. After it completes a dialog should appear asking you where to save the file, I would recommend saving it to your desktop (automatically selected) with the default name and file type.
If you have bought it from Amazon then you may have the Steam version of the game.
