Well, today the software doesn't work normally at all.
I opened the program and there was nothing wrong with it. However, it got crashed when I started drawing a line on the canvas. The program was so laggy, the laptop got stuck for a while and then the software quit automatically. I can still open the app and open the mbp file but I can't draw anything now.
DAMMIT MEDIBANG PLZ I STILL HAVE SOME IDEAS TO DO!!!!
