I'm not sure who supports the old perpetual licenses now but I have been unable to use Substance Designer for months. I purchased a perpatual license years ago and I am using 2018.2.2 every time I place a node the program closes. I can open Substance files, and import images, but as soon as I place a node it crashes. I can not afford to pay for the subscription service at the moment and I just want to be able to use the software that I have already paid for.
