Sounds like a corrupted project file. Can you still open it on you MacBook Pro?
What versions of FCP do you have on your computers? I hope they are the same versions. Because you can’t open a 5.1.2 file on a 5.1.1 machine, and vice versa.
If your project is corrupted, that’s not a real problem. Just remove your media drive, start up FCP and open your project. Create a new project and copy everything from your old project to the new one. This happens every once in a blue moon.
