Just delete the app and reinstall, you will have to reinstall the repositories again. I have tried this-

It worked perfectly for me, but others have had issues. Basically, follow the instructions and you can save all your repos and have them back on the new install of kodi in a few minutes. Give it a try, if not just do a fresh install.
Ta, uninstall and reinstall. Only had a couple of repositories so no real problem. I still can't get Sky on Live Mix and version showing is still 1.02 so have they given up or any tips? Other than that is sports devil the best default for live footie? It works but picture quality not good
