Hello, I am new to Kodi, today in my first day I successfully installed Kodi on a Raspberry pi 3.  Bad news is on my next move I installed some add-on which took over completely and now is showing me some weird skins and content.  I can find no way to uninstall it. Do I have to start from the beginning burning the SD card again with osmc?  There is got to be some files or configuration I can delete to reset everything to the beginning.
Thanks
