Hi, I've been using RSinjector for a long time now (at least 7-8 months from memory). Recently, I upgrade OS X to Yosemite, and although RSInjector seems to load and run fine, sometimes I'll try to run a song in "Learn a Song", and it'll just stop. If it doesn't need a tune it'll just sit on the song selection thing (where it shows "Rocksmith Recommends" etc.), or if it wants to tune/confirm tuning, it'll get through the tuning fine, then just sit there with nothing happening. This happens
