be sure your using the right patch i have enus so patch-enUS-9.MPQ works for me,at first i put engb in and it wouldnt start up right
and its in your data dirrectory in your wow client folder for me its C:\Program Files\darkrealm\Data\enUS (i renamed my wow so it wouldnt update anymore)
then in C:\Program Files\darkrealm\
put modeleditlive2.2.exe if your using the 2.2 patch and use it to run wow
i hope it starts working ok for you guys, the only other file is a .dbc file but its for the ascent core folder to use the client dont have .dbc files
