You cannot read Excel ".xlsx" form files using older versions of Microsoft Excel than the 2011 version of Office for Mac or at all in Numbers. You will either have to Upgrade your version of Excel on your Mac to "Office for Mac 2011", OR go back to your girlfriend's computer and resave the file using "Save As ..." and there select the ".xls" compatibility format instead of the default ".xlsx" version that the newer versions of Excel use.

Thanks for the reply. On my Mac I am actually already using MS Excel 2011 ...and Numbers '09.

Is your girlfriend using the new Office 2013 for Windows? If so, that may be why 2011 for Mac can't open it.
