Can't install PTV Live, help please.

Trying to install PseudoTV Live and having a bit of trouble.

Kodi Matrix Version 19.5 on an Nvidia Shield

Downloaded Lunatix' Repository, Installed fine, then installed PseudoTV Live Repository
and could not find a PTV Live install. The only item in the PTV Repository was a
"Look and Feel" folder.

Then downloaded the PTV Live Master zip file from Github and tried "installing from zip",
and got an error message "Could not install due to invalid structure".

Could use a bit of help installing.

Thank you!
