Hi,
First of all, thanks for creating EIN. It's brilliant and completely changed the way I work.
I've been using EIN for about 5 months now, using Windows 8.1/WinPython + MSYS + emacs 24.3.1. I run everything locally on a desktop.
Over the past months, I have started getting messages like this when I commands in the notebook from within EIN (I can interact with the same notebook on the same kernel from a browser without any problem at all).

Any idea what the problem may be? Thanks!
