XL: Error Message: Too Many Different Cell Formats

And if you ever have trouble opening this file, you may want to try openOffice.

http://www.openoffice.org, a 60-65 meg download or a CD

A few people have posted that they could open the file in OpenOffice, then
remove some of the formatting, save it and then excel would open that file ok.
