GameLauncher not working (Win7)

Edit: It won't run on my other XP either... wtp....
Is there any way to stop it from asking me to install the game if I already have it? I copied the files from the comp I use regularly over there to the same path but whenever I open game launcher, it doesn't work, and if I go through site, it starts downloading the game....

I tried to download it since it won't work off my flash drive, it downloaded the whole file or whatever through Nexon's downloader and then gave me Error -60: Download failed. :E
My XP works though so idk if they did something this morning.
