HI Ali Tsaiev,

Could you also post your dxdiag (system specs) as well?

Windows: Go to the Start menu and type ‘dxdiag’ into the search bar. Open that file and then click ‘Save All Information’. Post that text file here.

From your dxdiag it looks like you do not have Windows Service Pack 1. That update us required in order to run the editor. Could you try installing it from the Microsoft website and let me know if it fixes the issue or not?
