Repair from the Help menu. neither worked.

Using Office 2003 on Windows XP Pro

Trying to open a .xls file and I receive this message:

"This file is not in a recognizable format". The file is in a shared
directory with other excel files that open just fine. I tried to rename the
file with .txt just to see anything and the file was blank, however, the
file is 82K.

Any help would be appreciated.
