I have had older versions of Painter and upgraded to Painter 2020 when it became available. I have been using it without issue for some time. A few weeks ago I opened the program to use it and when I clicked on various brushes and other options the program did not respond. I tried accessing the program with my stylus and Wacom tablet. When this did not work I switched to using a mouse to make sure the issue I was having was not with the stylus or tablet. The program did not respond to my mouse either. I can see the cursor moving around the screen using either tool but when I click on brushes, or the paint bucket there is no response from the program. I tried contacting customer response but they have not helped me resolve the issue. I call and am giving a ticket number, I wait for an email and am given, at times hard to follow or incomplete directions. I have over 16 emails from support, one a day or every few days. but none of which have helped me resolve the problem. I'm loosing out on work not having my program.
