[users] I am unable to open a calc file I created

[Bette & Larry Gammell]

I am using openoffice.org version 2.3
I created a few different spreadsheets using calc. however one of them will not 
open no matter what I try.
It has opened and been updated in the past. Is there a way to open this or 
transfer the data? This is information that I can't lose or replace.
Thank you ,
Bette Luksha-Gammell
