Excel - unreadable content

Problem - when the client browser is Firefox, Excel displays the error message "Excel found unreadable content in ‘filexxx.xlsx’. Do you want to recover…"

Clicking yes allows the file to open with no apparent harm.

This problem does not occur with IE or Chrome. How does one keep this error from occurring?

BTW - currently using a cells dll with a file date of 3/12/2012
