excel eror
 utomatic update of links has been disabled.  If you choose to enable automatic updates of links, your computer may no longer be secure.  Do not enable this content unless you trust the source of this file

We have some Excel 2007 files that we cannot open.  These are legit spreadsheets that we created - they were not emailed in from the outside.  When opening these files, we get a popup on top of Excel

Microsoft Office has identified a potential security concern.

file path:  c:\.....file.xlsx

Automatic update of links has been disabled.  If you choose to enable automatic updates of links, your computer may no longer be secure.  Do not enable this content unless you trust the source of this file.

Whether we select Enable or Disable, Excel just opens up without any file displayed and no more error messages.  Any help would be appreciated.  thanks

Have you checked Unhide button on the view tab?
