Ya screw this! I tried the fix from Lyke's link but the files you download are zip and inside are not .pak but directories. unzipping gave error for all files it only makes the dirs.
So I deleted all content and downloaded it all again. And what do you think? same error. Because 1 patch installer didnt responded and shut down. The next patch installed without error. But still corrupted files when I try to loggin.
Its already bullshit that you need to download all the patches seperately.
ANY NORMAL SELF RESPECTING MMO MAKES THE CLIENT DOWNLOAD THE FULL LATEST RELEASE UP TO DATE VERSION. What crap is this that when you fresh download the game, you need to download the 10.0 version and then the freaking 2 GB patch (with crap 300 kb p/s) why dont they just put it in one download installer... Oh its to much work with every new update? well let them do something for their money for a change.
