After working for several hours on a movie, and saving them in 6 different files (one for each scene, that is), and then I close Moho 4.6 and leave the computer a while. When I return I can't open five of the files!!! It says that they are either a non-moho file, or from a newer version of moho. Very irritated over this bug, i try to open the files with my other computerm, using moho 5.0.3. But I can't open them ther either!

The message in moho 5.0.3 says:
Could not open file.
Error details.
Read error at line 1. In code file D:\develop\Im_tree\lib_moho\mohodoc.cpp, line 147.
I can't upgrade them with moho 4.6 updater. And i cant render them in batch-renderer!
I'm thankfull for any help!
