I couldn't get Paint Tool SAI. I downloaded the fudging license, payed the $69 dollars, and it wouldn't let me cut+paste the license into SAI. Oh wait, I couldn't! There was no "paste" option! How amazing is that?!
(I am so sorry if I seem mad. I'm just really sad. That in the next chapter.)

I got illustrator instead. It's pretty great, and I'm still learning.
