Apex clothing crashes everytime I apply clothing

I am very new to UE4. I want to apply a rob clothing using Apex Clothing for the thirdPerson View Character. I exported the fbx file and apx file from 3dmax. However, when I apply the clothing to the character, UE4 crashes. I tried a dozen of times and it just keeps crashing. I dont know what to change to stop that.

This is the message I got.
