Excel 2007: Lost Format

Hi
I have 10 worksheets with formatting --- shaded cells, font format of titles, underlining, bold fonts, etc. in a file. Well, they all disappeared!!!!

When I opened the file, I received the following message:
Excel found unreadable content in final.xlsx. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes.
When I clicked yes, all the formats that I spent hours on are gone!!

I guess the upside is that I did not lose everything.

Is there anything I can do? Has this happened to you? Do you know what causes it?

Thank you.

never heard of it before. if i had worked painstakingly on something for hours, i would have several intermediate backups, including a backup of the final product.

i assume you have made no backups.

have you googled your problem, perhaps?

i found this just by googling the error message.

also, are your service packs and updates up-to-date?
