COMBAT ARMS WONT WORK

ok so for some reason my combat arms doesnt work, I dont mod at all so everytime I try starting combat arms it just crashes, so I deleted all my nexon files and uninstalled it.

So Now when I went to download it again from the website, I agree and all but it wont download onto my computer

it keeps saying download but the bar doesnt move


I have windows 7 64 bit

Yeah but in the installing process the bars wont move
