Either/both should help.
Make sure that RAGE supports your version of the game. When RAGE opens in yellow/orange letters- Click on the little gear icon>once it opens up look at bottom left corner. If it has red text then it doesn't.
Delete your LSPDFR and Plugins folder(and any other mod files, ex .dll) and reinstall RAGE. Try it. If it works then reinstall Script. If that works reinstall LSPDFR but DO NOT replace any files. Skip all that are the same.
