I bought new laptop with win8 and office 2013. Have old excel file 2003 created. File is locked for any changes to certain fields with formulas as it is an invoice document auto complete for customer of mine. I have used it for 3 years. On new laptop as soon as I open it files formulas not working. But file works on other laptop with same specs as new one.

New laptop Acer Aspire E 15
