FCPX is frozen with spinning beach ball
My screen was frozen, with the forever spinning beach ball, and I could not click on anything. So, I forced quit FCPX. Now it's doing the same thing, every time I try and open it. I've tried re-starting the computer, and the only thing I have found on the web is some guy trying to sell a $5 program, "Event Manager X," with a confusing video on how to use his $5 program. Can anyone tell me how to fix this step by step in laymen's terms please? Thank you
