Hello, I need to know how can I reset the program to the defaults in a Mac.
I installed a brushes package and now PSS does not even start. It gives an error and the option to restart, but it just does not work anymore. I tried to delete it and reinstall again, but still gives the same error. I am desperate, so any clues will be very welcome.

Thanks in advance.

Ok, I got it: I had to delete the Paintstorm Studio folder on the Application support files, inside the Library directory, and got it reset to the defaults.
