Hi

I'm working on a movie and some problems are appearing. I made a research and nothing solved.

First, some project files was giving me a message when I tried to open: This project is unreadable or may be too new for this version of Final Cut.
Sometimes, a few minutes later, the project opened without any problem.

Today, I had a different problem: Unable to open project file.

I've tried to use digital rebellion's programs; save as txt in text editor and then open again as fcp; empty final cut preferences and render;... Nothing worked.
I can open my autosave and copy my edit, but I think that these problems will continue to appear.

I'm working in two machines, but both with the same FCP7 version, and four external hard drives G-Technology .

Does anyone knows what can it be?
Thanks
