Having tried to get PD to open for several months now, I find I am still unable. It bounces in the dock of my macbook and doesn't open. I tried looking at some other threads on this forum but none of them seemed to work

It occurred when I tried to change something in the settings (I think block size?)

I'm absolutely desperate to get this working again so I can make some more electronic music - this happened just as I was getting into it!

Is there anything I should be trying?

Cheers
