UNSOLVED MagicMirror on Windows 10

[esim]

I followed the tutorial here on the forum to install MM on windows 10
everything went fine all the way to the start of MM ( npm start) a black screen witha lot of
lines saying UNDEFINED, this was ofcourse because I was lacking the config.js file. After rename the sample config file, the npm start again, but with a black screen. The config is correct.
What could cause this?
