Hello Ptyler,
Nemesis is not a Kodi product. It is a 3rd party Build/Repository/Add-on whose only intention is to allow Piracy and Copyright Infringement.
The only
genuine Kodi add-ons can be found here...
https://kodi.tv/addons
The only Kodi
approved add-ons can be found in this forum where you posted this message.
Anything else out there is not Kodi.
We do not assist with the "anything else" add-ons... except to uninstall.
As nemesis is a build with some very heavy modification, the only advice you will get from us is a total uninstall and re-install by downloading Kodi from this site.
You don't give your hardware details, but the steps are as follows if using windows...
1. Uninstall Kodi using the Windows Uninstaller. Once this step is complete, then
2a. If you downloaded the Windows Installer go to c:\Users\
Your User Name\AppData\Roaming\
2b. If you installed from the Microsoft Store go to c:\Users\
Your User Name\AppData\Local\Packages\XBMCFoundation.Kodi_4n2hpmxwrvr6p\LocalCache\Roaming\
3. Look for the directory
Kodi and delete it.
4. Now you can download and install Kodi from here...
