Hi, I need help with the pen-pressure in this program. I use a Xp-Pen. I want to create a topic for it, but even after 2 days, the adms didn't accepted the previous ones I tried to create. Can I try to have an answer here in this topic? So far I can't really use the program in my job since it's not working with my tablet with the pen pressure aspect, and my option so far, if this problem is not being solved soon, is to ask for a refund.
