Excel problem

[cairnoscar]

I have a 2007 excel spreadsheet on my PDA which I also access from my PC. On trying to open today I get the message "Excel found unreadable content in file ---xlxs." It asks if I want to recover the contents anyway but when I click "Yes" I cannot open the file. All other Excel files are OK.

Any help would be gratefully accepted.

is it saved as a 2007 xls format?

Yes with Vista on the PC.
