If you have never been able to create a project I would trash Motion preferences in ~/Library/Preferences/com.Apple.Motionapp.plist. If that doesn't work I'd reinstall Motion from the App store after putting Motion application in the trash.

Hi, I have the same problem. I work on Motion 4, but i can't find the Motion preferences in ~/Library/Preferences/com.Apple.Motionapp.plist.
It's not there. Is it normal? Could that be the problem?

The reference is to your user library not the system library. If you are on Lion or Mountain Lion use the GO menu while holding down the option key and select library to go to your user library. See if you can then find the file. Also you can download Preference Manager from Digital Rebellion for free and it will do the job.
