KODI SUDDENLY STOPS WORKING PROPERLY

I have been using Kodi (Jarvis) for several months on my Macbook Pro 15 and it has worked fairly well. Yesterday I clicked on the KODI icon and immediately noticed something different. It took a much longer time to start up the program (approximately 40 sec.) than usual. When I clicked on a folder in my favorites to choose a TV episode, I was taken to the VIDEO FOLDER instead. This happens no matter what TV show or Movie I click on. I tried several things (cleared cache and providers, etc.) but nothing worked so I deleted the previous install of KODI and downloaded and installed Krypton. The same thing happens. It takes a long time to start up and will not play anything. I can see the TV show icon/folder but cannot access the seasons/episodes. Any ideas?
