This was my problem. This is an important distinction that was missing or i missed from other tutorials... ONCE EVERYTHING IS SETUP, RUN STEAM FIRST BUT NOT ROCKSMITH AND THEN US RSINJECTOR TO LAUNCH ROCKSMITH. Some how I missed that i got bizarre results by launching RSInjector without launching steam first. Thanks!!! I tried everything you have listed here but unfortunately still no success. I am stuck sitting with a couple Amps and stacks with no gameplay. Please help! I'm having this same problem
