Hello, I don't know how technical this is, but my FCE HD doesn't start. I tried several times after trashing the preferences and restarting the computer. It's been awhile since I've used it--about 6 months--but the last time I used it, it started and worked just fine. It loads up to "Profiling RT Extreme" and then stalls. I have to force quit it and it's marked as "not responding." I appreciate any help.
