I believe that means your models.pck corrupted (I could be wrong, it's been ages since I was in support-ish roll). I usually only get this problem if I direct download on google chrome or firefox. You should try to redownload the torrent if you can. http://epicpw.com/download/EpicPerfectWorld-v86.torrent
with the button that brings the launcher * verify * can not fix?
When I try to open the game I get this error, help !! * The image below is the error *
if you have backup copy of models.pack replace it in epw Client,it will be work i had same problem before
