downloading knights online

Well i have been trying to download knights online which is this free Internet game like maplestory just without the cartoon. But the problem is the first one that i tried everyone has been turning of my computer after i tell them not to for 3 days and then i get to find out that that patch file doesn't work and i tried a new one that takes way less time. Guess what. My sister turns my computer off after i told her personally not to. And so i just tried a different patch with the same one i did earlier. So i will tell you if it works or not.
