My pen pressure has suddenly decided to STOP working. I have uninstalled and reinstalled the tablet program, and downloaded the tablet updates but it still won't use the pressure! Does anyone know what I can do to fix this? I have an Intuos 4 Tablet, and I was in the middle of sketching when it suddenly just... STOPPED working. The PEN works, but my lines are all thick and jagged. I have changed the setting ont he brushes and everything and it still won't work. I usually work in SAI, and I opened up OC. It didn't work in there, either. I have looked around online, changed my tablet pen nib and nothing has worked for me 8C Any help would be AMAZING.
