Libre for months no problems great. Tried updating via Ninite

Ninite updated but updated via Libre now entire libre application freezing.
I can’t delete a message states “the feature trying to use is on a network connection that is unavailable”
Tried changing path “target msi” result unable to access.
Tried installing as repair and message read “not a valid installation package for product 6.02.1.
Error 1714 reads” the older version of Libre can’t be removed contact Tech Support" Help, please.
I need it up and running

This sounds like a Ninite problem (never heard of it, but then I use Ubuntu), not a LibreOffice issue. You would be better off asking in their support services.
