[split] Problems loading Kodi TV on Amazon fire TV

I try to get a new thread but somehow I couldn’t.
I bought a TV Box:
Minix Neo U1 Android 5.1 Lollipop Smart TV Box Mini PC Quad Core Amlogic S905 64-Bit Super HD 4K 3D Full 2160p H.265/HEVC With I8 Mini Wireless Keyboard.

I use it with a SmartTV. I had someone dowloading Kodi and I have Exodus.on it (I had to pay the guy). I don’t know anything about TV BOX (I tried to read the instructions when I receive the box and there was nothing about these things which is very disappointing.

A few days ago, I started to have problems:
The channels said I didn’t have authorizations, the shows’s videos were skipping (play/pause/play) – when it was on pause, it didn’t show that it was
on pause. It did this without any of us touching the play nor pause.

Someone told me that I had to update my Kodi. I don’t know which channel. Many times that I try a channel, it says that I don’t have the authorization
and tries to send me at that website https://olpair.com

Please help. I’m tired to have problems. I bought the most sophisticated one just to make sure not to get a cheap one and that I would not have
any problem. I feel sad to have spend that money and not having the service I deserve on it.
Thanks.
NB. If needed I could attach photos
