Game Troubles, Mabinogi

Im having some serious issues with this one game called Mabinogi. It seems like a cool game since you can pretty much make a virtual life but when I try to start the game it gives me an error with GameGuard that says this: “A GameGuard initialization error has occurred. Run again after rebooting your system or close any conflicting applications and try again”. This is pissing me off b/c I’ve restarted my computer like 7 or 8 times and it isnt working and I dont have anything running that could effect that thing. Im soo confused please somebody help b/c im sooo confused.
