Dear Chris,
Thank you! I did not realise this was problematic as it always worked fine in the past. I now followed your steps and managed to install mne without problems. And everything works great! However, to be able to scroll through the raw.plot() I had to change the matplotlib backend to
Qt4Agg (plt.switch_backend('Qt4Agg?), which might be useful for other users.
Thank you very much,
Dirk
