iMovie 10.0.3 - Non-responsive
I've updated to iMovie 10.0.3 for my MacBook OS X 10.9.2 and it's constantly non-responsive!! I can't even open it! How should I proceed? It's crashing at launch, leading me to force quit... I have restarted my laptop multiple time and it still doesn't work.
iMovie (iOS), OS X Mavericks (10.9.2)
