MapleStory Big Problem: Black Screen

Hey man, i have the EXACT same problems. After awhile my screen goes black and i have to minimize (ALT+TAB) and reopen to get it back to normal, but it continues happening and i have to restart maple. I have the same issue with the opening screen, if i let it play through and watch the video, the background is black, and it dc's me. I hope someone can help with this.
