P.S. I've tried rendering the same frame set as CPU 2 on others, and that's not working. So we know it's not just certain frames that it likes or doesn't like.

I'm now trying to do this on a 4th computer (my own, at home). This time, when I try to batch render, it gives me:

"// Error: Could not create command port : jeff:7835"

My name is Jeff, so I'm not sure what it's trying to access here but it sounds like a permissions thing? Ugh. Help?
