Neverwinter Nights 2 - Setup Problem

[freebard]

Hi there, its my first post.
I have NN2 on DVD as 7 cd image, and in each image there is rar parts. When extracting parts it gives error on cd-3, says:
" CRC error on Neverwinter Nights 2\Data\NWN2_Models.zip file."
but it keep up installing. on last part at the end it says "some of setup files or corrupted,please download a new copy of file and retry to setup." Anyway I cracked it and try to play game is working but in the chracter creating page there is no character And after game started everywhere is dark and in the right corner there is an alert "2d textures missing." I've gone to cd-shop and take just cd-3 and retry but hopeless ,its same error during setup. Do you know any way to fix theis problem, or upload this missing part "Neverwinter Nights 2\Data\NWN2_Models.zip" or at least check if this file exists or not, in game folder.
