Not responding when trying to open spreadsheet

Running US English Windows 7

I’m trying to open a spreadsheet I’ve been using for over a year now that opened Friday, April 18, 2014. Task manager and an error box from LibreOffice when I click X both say it is not responding. This same file opens fine on my Mac which also runs LibreOffice
