Final Cut Pro X continues to cause migraines

Final Cut Pro X is freezing again as I attempt to re-do one clip, which I have thus far been unable to match to what I had achieved in the prior version. My editing is an unfollowable path. I get so deep into it, I couldn't tell you how I got to where I get in the end. Hopefully re-doing this particular clip (even if I can't get to where I got before the trouble started) from scratch, the one that seems to be causing all the problems, will work and I can save it out to a file recognizable by YouTube. The clip I copied in to compare it to just froze the whole project, though. And I had to 'force quit' FCP X once again. So fatigued with all this, days and days of it.

And the worst of it is that I went on-line with the 'error code' (which I do not remember now), and found advice in the Apple Support Communities to delete all the render files associated with the project that refuses to share its video to a .mov file. I downloaded the QuickTime codecs recommended. Deleted FCP X. Re-installed it. Re-opened my project. All was there, except when I go into the files with Finder, all my files, the text, the images, everything is gone. It's pretty much a total disaster.

Then I ran out of batteries - I'm using my 46" TV screen as a monitor - for the wireless trackpad, so used the ones from the wireless keyboard and plugged that into some contraption I got from BestBuy with some of their BestBuy money that is a dock that re-charges the re-chargeable battery pack it comes with, using up the usb port that I could plug the original ext HDD into that I began the project on to see if all the original files still exist there, or if they, too, have been trashed in my attempt to get this sorry program, FCP X, to do its job properly. And I can't find the USB hub I got at a small computer store that even my old and dear iMac didn't like and wouldn't read serious programs from.

I used FCE for nearly 5 years, and never had a whisper of a problem with it. But it won't open these FCP X 10.0.8 files. I think FCP X a colossal waste of money at this point. I have never in all the years I've used Apple products experienced anything like this.
