Introduction and desperate appeal for assistance

Hi everyone.. My name is Nadine and I am from South Africa. Man alive.. I just LOVE Kodi!!

This weekend, I tried to update the new version of Kodi on my Android tv box (called Mediabox). After getting an error message, I went to download instructions where they advised I delete the previous version of Kodi. I did this and re-installed the new version (or tried to). When I go through the Google app store, it tells me that its not compatible to my system. When I download the Adroid arm and try to install, I get a parsing error. Is there anyone that can help me get around this error. Or help with the previous android java version.

Thank you..

Nadine
