I have a spreadsheet that I'm using in OOo 1.03.1. It was orginally a Excel 2000
file I opened it using OOo 1.02 and saved it as a OOo 1.02 spreadsheet file.
Once I accquired OOo 1.03. I simply opened it in 1.03 and have been using this
for sometime. I recently installed the OOo 1.1 beta2.  

When I tried opening it in OOo 1.1 beta2. I received the following message:

Error loading document file:///c:Documents%20and%20Settings/Ian%
20McKie/My%20Documents/Data/Daddy's%20Work/Church/Financial/Copy%20of%
20MONTHLYR2003.sxc:
Read-Error.
An unknown error has occurred.

When the file tries to load, the progress bar goes up to approximately 90% and
then the above message is displayed.

I will attach a copy of the file with this issue.
