Error code TT403 can happen for different reasons - it means that the program can't open the file. It might be because location that the file was saved to is no longer there, or not accessible. It could be that the file itself is somehow not accessible or is corrupt/damaged. If the program is not saving properly, try saving to another location, like your desktop.
