I have a problem guys, i just bought a brand new PC, everything was fine, until i decided to download Guitar Pro 5, whenever i open a File (guitar pro file) the notes aren't displayed at all!...I also tried playing Rakion but i can't even play it! after i Log In, my display goes black, then Windows Pop Ups again, as if the game had closed itself! I think the problem is the Graphics Card because my brother has crappy Onboard Video and he CAN play Rakion! What do you think?
