The instructions seem pretty idiot proof and yet its not working on my NA client. One thing I noticed different was that my enu.pak file was "1_enu.pak" instead of "2_enu.pak" .. though I wouldn't think that would have any effect.
I downloaded .rar, unzipped it, 3 files appeared in my L10N folder "abc.nfo; systemcfglocal.cfg; and a folder 'data'"
I renamed the 1_enu.pak to .bak. Nothing changed.
Then I went ahead and copied the 3 files into the "ENU" folder that was there and overwrote the folder named data inside "ENU". Nothing changed.
Last file I modified was the ENU.pak to .bak - Error your country cannot play this game. I changed the ENU.bak to ENU.pak and it the game plays fine, just no mob/player HP shown.
Any help or errors I made in what seems to be a straightforward process would be appreciated.
