I was using Final Cut Pro X and tried inputing an audio file into the timeline from a Finder window, and a popup window came up in FCPX and said something along the lines of "Your work can't be saved further. To avoid losing your work quit Final Cut Pro". I quit FCPX like it wanted me to, and waited a second, and reopened it. FCPX booted up and then... THE RAINBOW PINWHEEL OF DEATH!!!!! It kept spinning and FCPX stopped responding. My computer crashed and tried again. I had to use Activity Monitor to force quit it before my Mac crashed again. Has anyone had this error message before and how did you deal with it?
iMac, OS X Yosemite (10.10.1), Yosemite 10.10.2
