wPrime V1.56 is a huge update. In this version you have to use it with wPrime costomzier.

after i tried severval times finally find out how to use it:

1. download both wPrime and wPrime costomizer from the offical website.
2. unzip to same place.
3. open wPrime costomzier and choose old code (did not try vista coz i am runing XP SP2 32bit).When its done, open wPrime V1.56 and it can recognize your platform and open the original GUI.

But if you choose Basic Auto or Stability then it could not recognize the platform and get stuck in “geting CPU info” (at least for me.)  If you got any good way to costomzie it, please comment.
