Help I have a graphic problem

[arfatal54]

Hi there, I really need some help with the game. So yesterday I played it for the first time for about 5 hours without any trouble. Today I lunched it without any problem but then the whole game has horizontal green and pink bars everywhere. It is so bad I can barely read the things like "new game" and all. I tried the in game set-up thinking I f-up somewhere but nothing changed. then I asked a person I know who works with computer a lot and own the game and even he couldn't help me. So if any kind hearted soul ever encounter that problem and know how to fix it let me know cause I would really like to continue playing but in that state it is impossible.
