It won't allow me to run it anymore, it keeps crashing and says that Krita.exe has stopped working. I have reinstalled the program multiple times and yet it still does not work no matter how many times I have reinstalled it. Every time I try to make a new painting it will keep crashing. I would really appreciate it if you could fix that please.
We cannot fix that for you: this is a problem specific to your computer. You can try resetting the configuration: https://docs.krita.org/KritaFAQ#Resetting_Krita_configuration -- that might help if your system doesn't support opengl and you manually re-enabled it after Krita disabled it.
