Firestick nstaller problem

Hi all

Installing Kodi Jarvis onto new firestick, all went, installed fusion and Addon installer but every addon i try installing fails ( Phoenix, Genesis etc). Interest gly the addon installer goes through its "creating database on first use" every time i use it. When i try to install the video addon it comes up with "addon installer error"
Tried uninstalling and running older version of kodi but still the same issue - it happens with every addon

Any suggestions

Many thanks
