I cannot open about 90% of my Excel 12.1.1 Workbook files and some of my older Word files. If I revert to an older version of Excel on a backup, I can open them without a problem. Then when I re-save them and try to open with Excel 12.1.1 or 12.1.0, I have the same problem. I have contacted Microsoft but they never returned my email.
