Hello everyone,

I have an Excel worksheet that has a lot of information and a lot of pivot tables. When I try to open the file, I receive a pop-up which says, "Excel found unreadable content in 'filename'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click yes." When I click yes, it tells me that the pivot tables can not be recovered and I lose them. Does anyone know what might cause this and how it can be fixed? I apreciate the help in advance.
