Still getting this if anyone knows how to fix it."The memory could not be read"
So far as race codes go, i used to use Vx's morph races patch, and all the codes were dead simple. If you download and extract that to your data folder, the race codes are as follows:
90 - this is the base for every race
Then you have different 2 digit humbers depending on race-
01 - Human
02 - Orc
03 - Dwarf
04 - Nelf
05 - Undead
06 - Tauren
07 - Gnome [I think]
08 - Troll [I think, may be gnome]
09 - Goblin
10 - Belf
11 - Draenei
22 - Worgen
Then there's 00 or 01 which are genders. 00 is male, 01 is female.
So for example the code for Belf Female would read - 90101
All of this can be found in Vx2's every race thread, so credit to him for doing it.
