Price Tables plugin

Hi,

I am trying to import demo data for Game Addict theme but it show me those errors

Failed to import “top”: Invalid post type pricetable
Failed to import “Third”: Invalid post type pricetable
Failed to import “second”: Invalid post type pricetable

I also noticed there isn’t any “Price Table” plugin in my WordPress, as shown in your documentation.
I tried installing random price table plugins but I didn’t find the right one it seems because I still get the same error on each attempt.
