Rev 120 is an not public beta version. and there is no rev 120
There are 20 or so with different bugs in every version. If you want a working noggit and get support for it why not just go the documented way. Read the read me first post in the noggit sub board.
And BTW all the problems of 104 are answerd here in the board many times.
1. m2 model problem. Need to resave with taliis
2. Dont load WDTs from folder, but only form MPQS. So you need an patch MPQ with it inside your noggit wow directory.
3 Have problems to load stuff from some MPQ folders. Depends in the MPQLib version used in it. Just extract the MPQs with problems to your WoW folder.
Or subscripe to the beta group.
