Error Code -2147467259 (unspecified error)

Hello, I have recently got a HP Pavillon and when I ran maplestory I get an error -2147467259. I have searched around the internet but nothing has worked for me. Combat Arms also has this problem although, it just says it has stopped working as soon as it starts. I am running no hacks currently and I hope you guys can help me solve this problem. Thanks guys .

Check if your graphics drivers or directx are out of date.
It could be caused by corruption of game files, so you might need to re-install or re-download and then re-install the game.
