Hi! If it was Pixel8r 2 or 2.5, then sure! Send me an email (found on my ArtStation) with a copy of the receipt. If it was Pixel8r 1 or 1.5, that was always a separate product from 2. I do full version bumps for separate paid releases and incremental version bumps for their free updates.
Ouu thought that this is an update to previous one since I bought 1.5.3 version there, but if its separated from 2 then I guess Ill have to live with it for now :L
