I got a trial version of SAI, so does that mean I have to buy the SAI License software with a paypal Account? Because I never had a paypal account and I don't know how that works, can anyone tell me details on that?

Hey everyone, I've been having troubles finding a job lately, so I don't know when I will be able to post up my artwork, and be able improve more. So Just laying low for a while. So I just been down in the dumps lately. But hopefully be able to get back into posting art work again.
