go into your harddrive and go to /program files.....Nexon.....Warrock
then there shoud be 2 warrock icons in there.... click the one which says WRUpdater....
leave it to update.....
once it has finished (might take quite a long time) go to the KOREAN WARROCK HOMPEPAGE (just search korean warrock in google) and login....
then press the big START GAME button and it should automatically start....
