Hi whitepaw,

If you have AutoRecover on then go to the folder where your autorecovery files are saved. There is a chance that you 'may' find a good copy of your file there.
The file naming conventions are like this: ~ar7770.xar. Try opening those files in Excel, you may hit one that matches your file.

Please see more details about AutoRecover here:
