problem so spustenim hry Train Simulator 2014

Dobry den,
Mam Train simulator 2014 a ked dam play, tak pocas nacitavania mi spadne hra a napise: Railworks.exe prestal pracovat. Vsetke potrebne programy na spustenie mam nainstalovane ako napr. Directx, Nbidia Physic atd.
Spustam to na hernom notebooku: Procesor Intel i5 - 3,2ghz, 6gb ram, 2gb graf. Karta Nvidia 631 alebo nejaka podobna len to podledne cislo si nepamatam.
Spustam to na os: Windows 8, 64 bit a osobne si myslim, ze problem bude v nastaveniach grafiky Nvidia.

Vedeli by ste mi pomoct, ako mam postupovat?

Tam to nepise ze problemy so spustenim a pod.
