Cannot install any add-on on Cood-e! Cannot actually use Kodi!

Hi!

I am new to the Kodi experience, but until now I can’t get to make my new Cood-e tv box to operate.

By this I mean that I have made initial setup, connected to WiFi but cannot have access to any Movie, LiveTV, etc. When I try to install an add-on, there is a message reading something like “Installation Error. Check Log file”.

Although I’m not new to Windows, Android, etc. I spent two-three hours going back and forth, trying to understand what am I missing, but I cannot make it to work.

Should this be a defective device or I am doing something wrong, or what?

I would appreciate some help from Kodi veterans.

Thank you in advance.
