Excel/Excel Forward Compatibility


We have a complex Excel 2003 file to schedule our department that has been continuously updated since 2000.  The file contains no macros.  It works quite well in Excel 2003 and Excel 2007.  

When we try opening the file in Excel 2010, it indicates that "Excel found unreadable content.  Do you want to recover the content."  If we hit YES, the file opens, but loses most of its functionality.  We've re-installed Office 2010 to include all of its features, but it still doesn't work.

Any suggestions?




Of course you don't know what the issue is so fixing it specifically is difficult, but you might try copying the data including all formulas, etc and pasting it to a blank sheet in the 2010 version.  You will need the ability to open both the 2007 and the 2010 versions at the same time.

Hope this works.
