@sdetweil Thanks for the help! Used force to re-install MagicMirror again but still had an electron issue so I deleted the entier node_modules director as wel as the package_lock file and re-installed the modules. Then I had an error with MMM-MyCalendar which I fixed using the advice from here: https://github.com/jclarke0000/MMM-MyCalendar/issues/40
Most importantly everything works just fine now :) Thanks again!
