Since the last christmas update i cannot update my game, when i try to update via. updater it says "Error while checking patch for system/l2gamedataname.dat" and stops. I've already tried Deleting and re-install the game, already downloaded the lastest game files from the site and already tried to Run updater as an administrator. So please help me out. and english is not my main language so please forgive me if i did any mistakes.
