Did you extract the dbc's yourself, or download them from somewhere?
i used the ad.exe program from the Mogrein_WotLK_Repack, i followed all the steps via the forum, and have 3.0.1.8788 as wotlk beta version
Can someone please help?
It looks like your DBC files are old or you are missing them.
Try getting the most recent ones.
Check this thread out, should fix your problem.
