Well, I have installed Final Cut on my computer (V. 4), and after that installed aperture. Unfortunately, these two dont work well together, and all aperture could do was force close "because of a problem". So for the past month I have been running in 32 bit mode, no problem. Then I updated to 3.3. Apparently 3.3 takes the ability to force into 32 bit mode. So what can I do? Do I have to start from scratch and reinstall lion ( :O ) ???
