Okéééé mais voici le message que ça me marque :
No suitable graphics card found.
Could not find a Direct3D device that supports the XNA framework Reach Profile.
Verify that a suitable graphics device is installed.
Make sure the desktop is not locked, and that no ther application is running in full screen mode.
Avoid running under Remote Desktop or as Windows Service
Check the display properties to make sure hardware acceleration is set to full.
Comment faire ?
