i have this problem as well. i originally thought that it was because i downloaded the game to a different folder than the default folder. i just changed the location to the default folder and it's patching right now. did you not download it to the default folder as well?
hmmm, well i still have the problem as well. gameguard does indeed start. is there a way to change the game to windowed mode before actually playing the game? maybe it has a problem changing to fullscreen.
i dont think so. i still haven't figured it out myself. the only real way to figure out is to ask someone from the actual korean community i guess, since they would know more about their version than we do.
As soon as i changed my IP address the game let me in finely. I'm guessing they had the same situation of RO2 in which the only banned part of the IPs in North America. Jovi, try using a proxy so i can confirm my theory.
