Return of Reckoning

yes i did the first one but i only have 9 parts (z01-z09) and when i try to extract it, it says "unexpected end of archive"

i downloaded everything and when i launch it the error where the launcher couldn't find WAR.exe where the advice is to put launcher in same folder as WAR.exe but the problem is i cant find WAR.exe myself! please help.

sorry if this is a stupid issue im not the sharpest at computer stuff, but please ...
