Hi Sylvie,
Please answer these questions so we can help you better. I found numerous games with a name similar to the one you face an issue with.
- What is the exact name of the game and who is the developer?
- Were any changes made to the computer prior to the issue?
Lets try to play the game when the computer is in clean boot. In clean boot only Microsoft services will run so if there is anything conflicting with the game we can find out what it is.
Please refer to the steps on this article to perform a clean boot.

Please get back to us with the requested information and with the results of the troubleshooting.
