Addon is incompatible Loop

Hi
I have a XBMC box with KODI 16 installed.
I’m having a real problem with the continual looped message “Add on incompatible due to unmet dependencies ” message which appears to be applied to every Addon on KODI.

Can anyone advise me ?
I’ve tried removing the “Addon file” in Profile Directory-File Manager-Data Base but that hasn’t worked and I was only able to delete one of the two files, as the other would not delete. This seems to have created the continual looped message. Prior to this the addons where showing as 0% Downloaded
Any advice would be very much appreciated
Thanks in advance
Steve
