on ncwest and here the error was saying when i tried to run l2: "gameguard error. reinstall or update gameguard". here is a link of the problem of ncwest: http://boards.lineage2.com/showthread.php?t=262975 i changed browser, nothing. i deleted gameguard folder, nothing. i deleted and reinstalled game, nothing. i closed my anti-virus, nothing. my thinking is that probably is something in patch notes that doesn't let game to be lunched in some pc's. please check.
