.xls Excel 2007 error invalid file format ?

I keep having a problem when saving a particular .xls excel 2007 file. It is also being saved in 2003 compatable file format. When i attempt to re open the file after saving i get the message "file  Name".xls File format is not valid. When i press Control shift & I i get the error code 100109 displayed.

I cannot locate the error code shown so am at a loss as where to go from here other than recreate the file again (Bit of a ball ache job)

 

Has anybody any clues as to the error code an how to correct as i get this problem about once a month. 

thanks
