Kodi does not have a "maintenance tool" but certain piracy add-on repositories do which leads me to suspect you may be using and having trouble with http://kodi.wiki/view/Official:Forum_rul...ed_add-ons

If this is the case then we cannot help you. If I am mistaken then please elaborate on what add-ons you are having trouble with and provide a link to your http://kodi.wiki/view/Debug_log
