Many thanks! The .exe file actually solve the problem of the missing textures with some mobs, the char backgrounds still buggy but it must be my client. I will try to find a clear installation of wow as you say and try once more, thanks again! 

First of all: Really nice job! this with balsh char mod gives the game a very good fresh air

But... im having this issue: http://imgur.com/a/snXSE

The tauren, gnome and dwarf background are all buggy, idk if this is a matter with the game resolution or something. I play at 1600x900

also some creature models have black textures, i mean, the hydras have their heads painted in black, kobolds with the skull in their heads are all black too and sons of cenarius have their belts also in black.

Please help and thanks for your time
