Congrats, but you really shouldnt let people take advantage of you. Not even once. They are, after all, making money on the product, and if they use your images, they should most definitely pay. Email DAZ, and tell them about it. As for AutoFX, if i were you, i would demand them to pull back all the images, until payement is done. If they dont pay, sue them! Theyve had plenty of time to pay you by now and you have all the files for the images to show for.
