When opening Final Cut Pro it keeps getting stuck with the loading circle and I have to force the quit so please help?
I have a Macbook Air, still fairly new from July 4, 2014. Yesterday, I was editing some footage in Final Cut Pro, and the colored spinning circle kept popping up. I continuously forced the quit, as I couldn't do anything, and then I restarted and looked for updates (though there was none). I then deleted the app and reinstalled it, but it's still giving me the same problem. This morning, I created a new user account, and Final Cut Pro works on that account, but it took some time to find the exported video (I actually had to turn it off and turn it back on to find the video). Later today, I went onto the main account, where Final Cut Pro isn't working, and it's still giving me trouble, and then the Picture Preview program got stuck, as well, twice, where I had to also force it to quit. What's happening? How do I fix this problem?
MacBook Air, OS X Mavericks (10.9.5)
