Making a Transparent Background in Paint Tool Sai

In a lot of tutorials, there is a "PNG Save Box" that will pop up, allowing the user to save a transparent background. 
If you can't get this box to pop up, this tutorial is for you!
~~Sorry for the messy format!!!

PLEASE NOTE:
This is a tutorial for people who have the "cracked" version of Paint Tool Sai.
Please buy the full version to avoid this hassle and support the program!

I do not support pirating this program!
This is simply a helpful suggestion for people who may have downloaded the "cracked" version and cannot get the transparency feature to work.

The link for the "Online Photoshop" program used in the tutorial:

~~If the white areas of your art is "blank", but you want it to be white instead of transparent when saving it, please go back and fill in these "blank" areas with white color!!! Otherwise, they will become transparent with the background!
