I think this should go into a new post @Dreamxdevil, but I'll answer anyways.
Launch RagePluginHook, then immediately hold down SHIFT to open the settings. Go to your command line settings, and make sure you tick the box which forces the plugin to run in a windowed mode.
As for your LSPDFR plugins folder, have you installed any other plugins for LSPDFR? If not then you probably won't have one. If you add a simple callout pack, such as Variety Callouts, you will get a plugins folder if you install it correctly.
If you get any further issues, I'd make a new post (if you haven't already) inside of the LSPDFR 4.0 support forum so that you don't hijack this one.
