To restore your computer to an earlier date:
1. Make sure you save and close all programs
2. Go to start
3. Slect All programs
4. Slect Accessories
5. Slect Systems tools
6. Slect Systems Restore
When this opens you will be able to slect a date in the past that your document was opening o k.
This may take a little while and you will have to restart your computer.
This is what I do when all else fails.
