Problem at closing the game (black screen).

[NarutoRikudou]

I've been having this problem for a week, every time I open the game and try to close it or minimize it (by clickin in "EXIT", alt+tab, cntrl+alt+del or alt+enter) the screen just goes completly black and doesn't go off, no command works and the only thing I can do is to click the POWER button off my PC, do anyone know whats going on and how can I solve this problem??

Try verifying game files. Sounds like one became corrupted.
