group pricing per item NOT WORKING for me

I am using the latest version of the cart V3.8, and installed the laster version of group pricing per item. However, my shop doesn't show the group price even the costomer is belonged to that group. Also, every price show original price no matter on product page, product listing page , checkout, total, etc.

It seem totally not working~ Can anyone else help me tho fix it? as this pricing method is the mod i need the most~

I have follow all the installation instruction, but not working.

I tried it with Group A, Group B etc and tried renaming the group names and neither seems to work.

What change in the shopping_cart.php?

Did anyone get this working?
