HI,

I have been using open office for a while now. I'd used previous version of open office and I'd recently downloaded the latest version of open office. But there's this one file that I'd unable to open. I'd created and used this file frequently with the previous version of open office. When I tried to open the file, an error message box popped up and said "read error - unknown or unsupported Excel file format".

Please help.

I did not find the right solution from the internet.
