what I have found with playing with this combo lately is if you fire up DCS first, let it autoconnect to the servers SRS when you join the multiplayer server, then open virtual cockpit after you select your aircraft, it work fine for that session. Then the next time you use DCS, the DCS SRS plugin never connect to the SRS application. The only fix I have found so far is uninstalling SRS, removing the following directory left over "C:\Program Files\DCS-SimpleRadio-Standalone". Then reinstall SRS, and relaunch how I first describe how I get it to work. I'm assuming virtual cockpit when it injects is messing up the SRS scripts
