I had to register and give a proper FIX to this problem.
I was encountering the same issue of launching the game and it was just crashing to desktop after a black initial screen.
After updating DirectX,installing .net..updating audio drivers and what not... i came across the solution to another game with same behavior.

(if these steps are not present at your control panel just skip to step 5 and add both rnr.exe in bin folder, and rungame.exe)
That did the trick for me!
Happy Gaming.
