Cyberface 3D help (anime)

Basically I'm trying to make my own modified version of anime characters by editing created character's cyberfaces. So I've tried modifying some faces that I downloaded already and changed the face with photoshop but then whenever I use blender, every time I try to import my .n2km exported file into the nba2kx mod tool, it gives me an error message saying

java.io.IOException: Model Part is Not Matching
Resource:553
Import: 280

or something similar like Resource: 125 Import: 124
This one time it worked and then it was basically a big cube with random jaggered lines going in all directions
At this point I'm starting to think it's my exporting plugin for .n2km because it's happened with all my files and I've been sitting here making these models that don't even work

I've also tried the 3dm tool but it gives me errors in Chinese

Please help me if you know what's wrong, this is really getting frustrating!
(Btw If I get my mod working I'll send links to it, and I'm doing every team from KnB!)
