I'm not sure why, but I think I did delete my ".PyCharmCE2017.2" folder and several other hidden folders just before it stopped working because my account was out of space, so I'm wondering if this could have been the cause? Both Pycharm and ipython are not able to import MNE anymore. <br></div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"><b><u>2.
