I get a workbook created in an earlier version of Excel sent to me each week and when I try to open it I get the message "Excel found unreadable content in XYZ.xls. Do you want to recover the content of this workbook?". On clicking Yes the workbook always opened in Excel 2007 but does not in Excel 2010 - nothing happens in 2010.

Is there some way of opening this file in 2010?
