If you want to run LSPDFR configurator:
Make sure you have legal copy of GTA V.
Make sure you run LSPDFR Configurator.exe as an Administrator.
If you can't still use or run configurator, there's a way how you can configure some things:
Run lspdfr.ini config file in same directory where configurator is. Open him with WordPad or Notepad. There you can edit a lot of things.
And about RPH, why you can't run and post a log?
