Error message – Aeon Nox: …. Help PLEASE

Hello Everyone,

A friend of mine is having problem running Kodi on her Mac Book Pro that I installed for her when she was visiting California last year. KODI was running fine until it stopped couple of weeks ago. Every time she tries to start KODI she gets the following message:

Aeon Nox:SiLVO Repository
Add-on is incompatible due to unmet dependencies.
Would you like to disable it your system?

There are two EMPTY clickable boxes as options. Tried clicking on both boxes, but nothing happens and need to reboot the MacBook Pro to get out of KODI.

Running Kodi 16.1 ver.
