You have to do everything like u want to have hacks for the first time. Begin from updating legit client and unpacking fresh data files. My crc works on win xp, 7 32/64 bits.
P.S. This kind of explanation u can find in other tutorials and I'm not telling that it's my work, it's just a help for people who don't get it well (ofcourse CRC folder was build by me).
Give a big thanks for people who have made the pack manager and reXIGNation !!!
