My technical skills and know-how with Source Tree are pathetic at best, so you'll have to be very, very slow. I use Source Tree for Unity, and the file still runs perfectly in the application, however a corrupted file formed in my folder. I removed it (perhaps foolishly) and now I receive the titled error. Source Tree will no longer allow me to access my file or commit further to it. I have no idea where to start. Thankyou for any help you can provide.
