Installed through Launcher. Everything seems to work fine ... except when I quit after deleting a Replay file. When I quit without deleting a replay file, I get taken right back to the launcher with no problems. I can Ctrl-Alt-Delete and run Task Manager to quit. Behavior of rF2 is the same after that. I've only been deleting replay files made with the latest install. Do you need more detail? Hope this helps. I'm loving rF2, esp. the vintage cars.
