Sometimes, a lot, I create a project, and save it, when I open it again, all the files are replaced by the name -1, they still work, and the timeline is completely empty... bye bye, hard work!

The last time this happend, I started to save under different filenames. But still, MIEF 1, 2, 3 and 4 are still good, but 5, 6, 7, 8 and 9 are broken...
