So, at late August, my trial for SAI has already expired.

But after I finished a sketch for a reference sheet of my OC Flyolet, I opened up SAI. Then of course, it told me that it expired. But, I went to the desktop and clicked on a random file I saved from SAI. Then after that, I found out I could still save that file AND open a new/existing one, but not when I didn't open up that random file.

So I found out I STILL can use SAI, even if I don't have to buy it! :D I was so worried that I thought I might not be able to use it anymore...
