Braking node-red

[JaniKallankari]

Newbie to node-Red so be patient. I tryed to add led to my working flow but whole UI stopped to work once installed uninstall node-red-cotrib-ui-led. I after uninstall node-red-cotrib-ui-led I still have problems with ui_base. Any one know how to reset (fresh install) node-red? It seems to be very easy to broke with broken pagages...

Here is log of start up with uninstall node-red-cotrib-ui-led:
