Sketchbook legality

[khaira.hudna3035]

Hi, i using sketchbook from they were free on dekstop (Autodesk Sketchbook ver 8.7.1). I realize- now they're not free anymore. Is that legal if i still using the old one? (for commercial purpose). Thanks!

Old free software stays free: whether you are violating that old software's terms or not, you can explore those yourself in that application.
