Hello CurvEdge !!
I had the same issue with some of the newer games, which resolved for me here and should help you is to do the following:
Remove the current Raptr (uninstall) then restart the PC, then download the latest version of the site Raptr and install this new version, do log in to your Raptr account and re-scan the installed games.
See it solves for you !!
