Problems with SDK on Mac OS X "Lion"

Hi everybody,
I downloaded jMonkeyEngine 3 for Mac OS X, unzipped it on my “Downloads” folder and it worked fine.
Then I tried to move it to my Application folder, but it shows a weird GUI, with some button hidden and others with a question mark.
I tried to unzip again in my Application folder and tried to download it again, but nothing, same problem.
Any idea?

Maybe the settings directory was created with the Downloads folder as application location, try deleting the settings folder and then start it again from Applications:

@normen, now I can run JMonkey SDK from “Applications”, thanks! But now the GUI is completely gray. Buttons work, but they’re invisible. Any idea?
