I just purchased L&L express for FCE. The issue I have is that in the filters tab, the Lock and Load filter is kind of blank. I don't see the logo, or register button (which I need) or anything. The motion tracking is also blank. I can't click on it. Most of the controls are there from what I can tell, but they are greyed out.
This is probably an FCE issue. Please try to quit FCE, remove the FCE preferences file and restart FCE.
If this doesn't help, can you please check the log file for related error messages?
