Fatal Error: All Viewports (Except Preview) Frozen, All Buttons/Scrollbars Broken

Question

So, this happened:
As you can clearly see, iMovie has completely destroyed itself. All viewports (aside from the preview window) have shut down, although can still be used for navigation (seeking can still be done on the now-invisible film reels), the scrollbars present on each port are no longer functional, and not one of the buttons responds to a click. Even the Graphic EQ is no longer functional. The Inspector window does still work, though is completely useless when I can't see what I'm editing. The drop-down windows do drop-down, but any command I use renders no result.
It should be noted that quitting and restarting iMovie remedies absolutely nothing, as the problem is still present. Even when I start the program with a different movie file, iMovie loads this one and refuses to change. It will, however, load the preset image of the alternate movie file initially, though will switch back almost immediately.
I really need help with this. Anyone know what's wrong, or better yet, how I can fix it? Any help is appreciated, thank you so much!

Answer 1

Chances are you are looking in the wrong place. You need to look here.
Navigate to Macintosh HD/<Your User Name>/Library/Preferences.
If you look in Macintosh HD/Library/Preferences, you will not see it. This preference file is specific to your user account.
Another way to check if you still can't find it is to log in under another user account and open iMovie there. If it works, you know that the Preferences file wil probably solve it. If not, you probably need to reinstall iMovie or OSX.
