You may post your Lua-File at http://pastebin.com/ and give us the link. It's much easier then for people to help you. Have you set coordinates for every Race, the ones in the LUA-File are not for ingame, they describe the position of the RaceIcon in InterfaceGLUESCHARACTERCREATEUI-CharacterCreate-Races.blp. Check this first.Additionally, have you insert new Icons? if not, just use the Coords of another race temporarily to test it!
pachenUS2 There are patch 2 and 3 original from blizzard.Have you overwriten them?It must be named patch-enUS-4.MPQ
We are not your personal coding-error finder, imho. Try finding things like nil-values etc yourself by improving your coding skills. Editing a line, getting a new error and asking here again won't help anyone.
